Strength Checker for Password Systems: For a given password system, calculate the search space for a general user and a lazy user. Suppose only 11 special characters can be input. Program with any language. Input (by the evaluator): 1st line: number of characters 2nd line: numbers allowed [Y/NJ? must be included [Y/NJ? 3rd line: letters allowed [Y/NJ? case sensitive [Y/NJ? must be included [Y/NJ? 4th line: special character allowed [Y/NJ? must be included [Y/NJ? Output: 1st line: The search space for a general user is (). 2nd line: The search space for a lazy user is 0. Example: Input: 6 YY YYY YY Output: The search space for a general user is 1.43*10^11. The search space for a lazy user is 2.68*10^9.

- A spell checker in a word processing program makes suggestions when it finds a word not in the dictionary. To determine what words to suggest, it tries to find similar words. One measure of word similarity is the Levenshtein distance, which measures the number of substitutions, additions, or deletions that are required to change one word into another. For example, the words spit and spot are a distance of 1 apart; changing spit to spot requires one substitution (i for o). Likewise, spit is distance 1 from pit since the change requires one deletion (the s). The word spite is also distance 1 from spit since it requires one addition (the e). The word soot is distance 2 from spit since two substitutions would be required. a. Create a graph using words as vertices, and edges connecting words with a Levenshtein distance of 1. Use the misspelled word “moke” as the center, and try to find at least 10 connected dictionary words. How might a spell checker use this graph? b. Improve the method…Introductory: The Caesar Cipher technique is one of the earliest and simplest methods of encryption techniques. It is simply a type of substitution cipher, i.e., each letter of a given text is replaced by a letter some fixed number of positions down the alphabet. For example, with a shift of 1, A would be replaced by B, B would become C, and so on. The method is apparently named after Julius Caesar, who apparently used it to communicate with his officials. Thus, to cipher a given text we need an integer value, known as a shift which indicates the number of positions each letter of the text has been moved down. The encryption can be represented using modular arithmetic by first transforming the letters into numbers, according to the scheme, A = 0, B = 1 ,…, Z = 25. Encryption of a letter by a shift n can be described mathematically as. En(x) = (x+n) mod 26 (Encryption Phase with shift n) Write an algorithm and implement a program in C to read the data from a file (called…Java or C++ program to display the given output -----Library System----1.

- Artificial Intelligence - Local Search Starting from a randomly generated state of the 15-puzzle game (https://en.wikipedia.org/wiki/15_puzzle), steepest-ascent hill-climbing (the vanilla version of hill-climbing search) gets stuck 76% of the time, i.e., solving only 24% of problem instances. But it works very quickly, i.e., it takes just 6 steps on average when it succeeds and 5 steps when it gets stuck. In contrast, if sideways moves are allowed, this raises the percentage of problem instances solved by hill-climbing from 24% to 81%, with the success at a cost: the algorithm averages roughly 7 steps for each successful instance and 32 steps for each failure. Now suppose that we are implementing random-restart hill climbing (i.e., if a search fails, it keeps to try, and try, until it gets a success) by the following two versions: one uses vanilla steepest-ascent hill climbing, and the other one uses hill climbing with sideways moves. Can you please tell which version of…Loops summary: for vs. while We have now seen that Python has two different loop constructs: the for loop and the while loop. The while loop is more powerful than the for loop, since it can be used in situations where the number of iterations isn't known in advance. For example, the following while loop answers the question: "If a population of bacteria increases in size by 21% every minute, how long does it take for the population size to double?" minutes = 0 population = 1000 growth_rate = 0.21 while population < 2000: population *= (1 + growth_rate) minutes += 1 print (f"{minutes} minutes required.") print (f"Population = {int(population)}") This would not be well suited to a for loop - we are trying to find out how many times the loop will run, and a for loop expects to know how many times it will run before it starts. In contrast, the for loop is a special case of the more general while loop, meaning that any program written with for loops can be rewritten to use while loops.…please code in python You place a pawn at the top left corner of an n-by-n chess board, labeled (0,0). For each move, you have a choice: move the pawn down a single space, or move the pawn down one space and right one space. That is, if the pawn is at position (i,j), you can move the pawn to (i+1,j) or (i+1, j+1). Ask the user for the size of a chessboard, n (integer). Find the number of different paths starting from (0,0) that the pawn could take to reach each position on the chess board. For example, there are two different paths the pawn can take to reach (2,1). Look at the diagrams below to convince yourself of this. You can see the four paths that you can take by move 2. Start -> Move 1 -> Move 2 (0,0) -> (1,0) -> (2,1) (0,0) -> (1,0) -> (2,0) (0,0) -> (1,1) -> (2,1) (0,0) -> (1,1) -> (2,2) Print the board with the number of ways to reach each square labeled as shown below. For example: Enter a board size: 4 1 0 0 0 1 1 0 0 1 2 1 0 1 3 3 1
- Problem Description Learn Clojure In this problem, each person in the social network takes a specific time to send the message(time is an integer). A specific newbie in react(let's call him NB) wants to post a question to a ninja(let's call him NJ) on the network. Find out how long a specific message takes to reach NJ from NB. The social network is given as the input as follows. The first line is a number which is the number of people in the social network. The next following lines are the actual members of the social network whose names are written in separate lines. Following that is the number of connections, followed by a new line separated list of connections given as . Then on the next line is the person who wants to send the message(NB's id in our case) and on the next line is the person who is the intended recipient(NJ's id). The output should be a single line consisting of the time it takes to send the message through or -1 if the message can't be sent. INPUT FORMAT total…Artificial intelligence (Question - 6) ======================= One variation on the game of nim is described in Luger. The game begins with a single pile of stones. The move by a player consists of dividing a pile into two piles that contain an unequal number of stones. For example, if one pile contains six stones, it could be subdivided into piles of five and one, or four and two, but not three and three. The first player who cannot make a move loses the game.(6.1) Draw the complete game tree for this version of Nim if the start state consists of six stones.(6.2) Perform a minimax evaluation for this game. Let 1 denote a win and 0 a loss.Java program Implement getName : returns the name of the student in the following format {lastname}, {firstname} increaseAge : increase age by one, this returns nothing toString : returns the details of a student format is lastname,firstname,age,minor or adult
- Write in C Language Spilitology Yosef is a peculiar fellow. He introduced the idea to study a string by splitting it into two, and he called it Splitology. Why split a string? We do not know. Didn’t we say that Yosef is a weird one? Yosef is interested in one particular type of string, a palindrome. A palindrome is a string that is the same for both forwards and backwards. Example of palindrome strings are “ada”, “taat”, and “radar”. On the other hand, string such as “taman” is not a palindrome; notice that “taman” becomes “namat” if read backwardsand it’s not the same as “taman”. As the idea of Splitology is still new, Yosef is investigating whether a string can be split into two non-empty strings such that each string is a palindrome. For example, the string “malamini” can be split into “malam” and “ini” while both of them are palindrome. Another example is “ababab”. It can be split into “aba” and “bab”, and both of them are palindrome. Note that “ababab” can also be split into…Lab Assignment 1: Vigenere Cipher Overview: You are required to implement the Vigenere Cipher using any programming language of your choice. Your program should be able to encrypt any given message written in text. Your program should allow the user to submit a message for encryption (the message must use text only). You should use the following message to demonstrate the encryption: “Party on the Quad." Your program should allow the user to input the key for performing the encryption. Please use the following key to demonstrate the encryption process: "Homecoming."Blackout Math is a math puzzle in which you are given an incorrect arithmetic equation. The goal of the puzzle is to remove two of the digits and/or operators in the equation so that the resulting equation is correct. For example, given the equation 6 - 5 = 15 ^ 4/2we can remove the digit 5 and the / operator from the right-hand side in order to obtain the correct equality 6 - 5 = 1 ^ 42. Both sides of the equation now equal to 1. Observe how removing an operator between two numbers (4 and 2) causes the digits of the numbers to be concatenated (42). Here is a more complicated example: 288 / 24 x 6 = 18 x 13 x 8 We can remove digits and operators from either side of the equals sign (either both from one side, or one on each side). In this case, we can remove the 2 from the number 24 on the left-hand side and the 1 from the number 13 on the right-hand side to obtain the correct equality 288 / 4 x 6 = 18 x 3 x 8 Both sides of the equation now equal to 432. Here is another puzzle for you…
