2. Characters in Strings A large part of the text processing done by computers involves reading user input and figuring out what it means. We'll do something like that today: given a string supplied by a user, we report (1) the total length of the string, (2) how many alphabetic characters, (3) how many numeric characters, (4) how many vowels (a, e, i, o, u) were in that string, and (5) how many of the alphabetics were upper-case. For example, if a user input this line: the program would say: String length: 30 James Bond, 007, works for MI6 Alphabetics: 19, upper-case: 4 Numerics: 4 Vowels: 6

- Part 6: Boolean Logic Expressions Boolean expressions are types of logical operations that we can perform on true and false values. Note that the word Boolean is always capitalized because it was named after its inventor, George Boole. Boolean algebra is a very important topic in computer science, and if you haven't learned it before you definitely will in the future. However, for our purposes we are only interested in how we can use them to manipulate binary numbers. The way we use them on binary numbers is by treating 1 as true and 0 as false. From this point on I will be using 0 and 1 instead of false and true. There are many types of Boolean expressions, but the three most important ones are AND, OR, and NOT. AND takes 2 operands and will output 1 if they are both 1, or 0 otherwise OR takes 2 operands and will output 1 if either one is 1, or 0 if neither is 1 NOT takes 1 operand and reverses it: 1 becomes 0, and 0 becomes 1 We can represent this behavior using something called a…Question 4 - Algorithm Design Imagine you are a treasure hunter standing at one side of the river. There are n (a positive integer) stones on the river. They are aligned on a straight line and at the nth stone, there is treasure waiting for you. Your target is to reach the nth stone. For each move, you have the choice of either walking (move one stone ahead) or leaping (move two stones ahead). Also, you are not allowed to travel backwards. Design an algorithm that calculates the number of ways (sequences of walks/leaps) that get you to the treasure stone. You should clearly explain the algorithm and demonstrate the correctness of the algorithm with a complete proof. Here is an example. For n = 1 5, there are 8 ways: Method 1: walk → walk → walk → walk → walk Method 2: walk → walk → walk → leap Method 3: walk → walk → leap → walk Method 4: walk → leap → walk → walk walk Method 5: leap → walk → walk → Method 6: leap → leap walk Method 7: leap → walk → leap Method 8: walk → leap leapA computer word is: A A group of bits that can be treated together but in any order within a computer. B A sequence of bits that can be used together in a byte. C A group of characters that can be treated together as a string. A group of bits that can be processed together as a unit. D

So na left is an anagram of felt and vice-versa. A Super Anagram is a special kind of So anagram. A Super Anagram is an anagram whose first and last letters are the same. So if Your program needs to read in two words on a single line. If the pair of words are Super Anagrams of each other, print out Super Anagram!. If the pair of words is not a Super Anagram (so a human couldn't read it), then print out Huh?. For one-letter words, the first letter is the last letter. So, for example: Enter words: brain brian Super Anagram! and another example: Enter words: too two Huh?Examples If the input is: 130 50 130 the output should be: (80, 0, 80) Note: You will always have at least one zero in the resulting tuple. If you had (130, 50, 130) you will have (80, 0, 80). If you had (100, 5, 100) you will have (95, 0, 95).

- explain and prove the algorithm You found a lost civilizations' library and you are interested in its alphabet of 7 strange characters. Each book has a title in this alphabet and you hope that the books are arranged in lexicographical order on the bookshelves. You would like to know whether the order of the books uniquely determines the order of the characters of the alphabet, or if there is insufficient information, or whether even such an order cannot exists (meaning that someone must have shuffled the books). Think of the input as a list of words without spaces from the alphabet "a-z", and the question is the order of the characters "a-z" in the examined alphabet. Try to find an algorithm which solves this problem in time linear in the size of the input (that is, the number of characters on input). You may assume that each character appears at least once. Don't assume that the size of the alphabet is a fixed constant (like 26); treat it as a variable n, and let L be the total number…According to the mathematical operation number entered from the keyboard, for example; 1.) collection 2.) subtraction 3.) multiplication 4.) compartment Type the codes of the c language, again finding the result of two numbers entered on the keyboard. for example; please enter a number between 1 and 4: 3 enter the first number: 12 enter the second number: 3 result: 36Python Algorithms Part 1 – Binary SearchLet's play a little game to give you an idea of how different algorithms for the same problem can have wildly different efficiencies. If I choose an integer from 1 to 16 and ask you to guess what the number is, you can keep guessing numbers until you hit on it. When you guess wrong, I tell you whether you are too high or too low. Once you've guessed the number, think about the technique you used to decide each of your next guesses.If you guessed 1, then 2, then 3, then 4, and so on, until you guessed the right number, you used an approach called “linear search,” meaning you guessed the numbers serially and sequentially, as if they were lined up in a row. This is definitely one way to find the mystery number, but it could require as many as 16 guesses. However, you could get lucky, if the number was 1, you’d only need 1 guess. Using a linear search process, on average, you'd need 8 guesses.There is an approach that is more efficient than just…
