There is an NN of components, represented by the strings S1,S2, .... SN. The chef took all the ingredients, put them in a cauldron and mixed them. In the cauldron, the letters of the strings representing the ingredients are completely shuffled, so that each letter appears in the cauldron as many times as it has appeared in all the strings combined; now the cook can take out one letter from the cauldron at will (if that letter appears in the cauldron more than once, it can be taken out that many times) and use it in a dish. Complete Food is a "chef" chain. Help the chef find the maximum number of complete meals he can make! Input 1 5 codechef chefcode fehcedoc cceeohfd codechef Output 5A 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…
- This is what you will need to do for the C programming: 1. In quiz1.c implement digit_sum_base function using recursion that calculates the digit sum of a number's presentation with base as base. For example, if base is 2, a binary number, digit_sum_base(5, 2) should be 5's binary reprentation 101, adding up all digits together and we have 2. digit_sum_base(1234, 10) should be 10 = (1+2+3+4). You may assumen is always non-negative integer and base is an integer between 2 to 10 inclusive. 2. In main.c implement the main function so that when we run the program this is what happens: %./main Enter an int: 0 Enter a base: 10 answer is O. $ ./main Enter an int: 1234 Enter a base: 10 answer is 10. $IN JS LANGUAGE Given the above parameters, implement a function that returns a string representing the plant (see the examples below for a better visualization). Examples plant("@", 3, 3, 25) "---@@@_@@@---@@@"Determine whether a string is a palindromeA palindrome is a string of characters that reads the same from right to left as it does from left to right, regardless of punctuation and spaces.The specifications for this assignment are: •Write and test a non-recursive solution in Java that determines whether a string is a palindrome •Your program should consist of at least two methods: (1) the main method (2) the method which performs the task of determining whether the specified string is a palindrome. You should name this method isPalindrome. You should name the class that contains your “main” method and the isPalindrome method FindPalindrome. •You must use a Stack and a Queue in your solution: Write your own Stack and Queue based on the Vector in the Java API and use those in your solution. You should name those classes StackVector and QueueVector respectively. You already have access to the relevant exception classes and interfaces for the above ADTs. •All of your belong to a Java…
- Write these in Pseudocode #1a – In pseudocode, write a call to a function that passes 1 Integer variable and 1 Integer array, and saves a Boolean value in return. #1b – In pseudocode, write the function that accepts 1 Integer and 1 Integer array and returns a Boolean. In the function, search the Integer array with a for-loop, and if the Integer parameter is found in the array, return false. If the Integer parameter is not found, return true. #2a – In pseudocode, write a call to a module that passes 1 Integer variable, 1 Real variable, 1 String constant, and 1 String literal as arguments. #2b – In pseudocode, write the module header that accepts 1 Integer, 1 Real, and 2 Strings as parameters. #3 – This pseudocode has multiple problems. Fix the calling statement and the definition below so that the routine accepts 3 grades as parameters and returns the average into a variable.…C++ in visual studio: Implement it completely with copy constructor, overloaded assignment operator and destructor. Then, in main, type an application that creates 2 numbers, sums them, and assigns the result to a new number. for example ; Number 1 (18,32) Number 2 (15.09) - - - - - - - - - - - + Number 3 ( 33,41)IN JAVA Create a function that takes a string and returns the number of alphanumeric characters that occur more than once. Examples duplicateCount ("abcde") → 0 duplicateCount ("aabbcde") → 2 duplicateCount ("Indivisibilities") → 2 duplicateCount ("Aa") → 0 // Case sensitive
- Write in C++ Alice is trying to monitor how much time she spends studying per week. She going through her logs, and wants to figure out which week she studied the least, her total time spent studying, and her average time spent studying per week. To help Alice work towards this goal, write three functions: min(), total(), and average(). All three functions take two parameters: an array of doubles and the number of elements in the array. Then, they make the following computations: min() - returns the minimum value in the array sum() - returns the sum of all the values in the array average() - returns the average of all the values in the array You may assume that the array will be non-empty. Function specifications: Function 1: Finding the minimum hours studied Name: min() Parameters (Your function should accept these parameters IN THIS ORDER): arr double: The input array containing Alice's study hours per week arr_size int: The number of elements stored in the array Return Value:…A postfix expression is an expression in which each operator follows its operands. Figureabove shows an examples of postfix expressions.The advantage of postfix form is that there is no need to group subexpressions in parentheses or to consider operator precedence. One may have used pocket calculators that require entry of expressions in postfix form.Write a program that simulates the operation of a calculator by scanning an integer expression in postfix form and displaying its result. The program should push eachinteger operand onto the stack. When an operator is encountered, the top two operands are popped, the operation is performed on its operands, and the result is pushed back onto the stack. The final result should be the only value remaining on the stack when the end of the expression is reached. This program scans a postfix expression and evaluates it. The Postfix expression must be followed by a space and a '?' to mark the end of the expression. One must use stack and the…Question 4. Recursion write a Java program.A perfect number is a number whose factors, excluding the number itself, also add up to that number.For example 6 is a perfect number since its factors (other than 6 itself) 1, 2, and 3 also add up to 6 (i.e.,1+2+3 = 6). Write a program that uses a recursion to determine if an integer provided by a user byusing Scanner object is a perfect number or not
