Construct a TM M4 which accepts the language { w2w | w in {0,1}* }. This means, any input that comprises two copies of a binary string w separated by a single 2 symbol should be accepted. Any other input should be rejected. The input alphabet is {0,1,2}. The tape alphabet contains 0, 1, 2, _ and you may use additional symbols 3, 4, ..., 9 if you wish (M4 can be constructed comfortably with just one additional symbol 3). The tape's content after M4 halts does not matter. Submit a representation of M4 as described above.

Implement a function, countVowels, which takes in a string and counts the number of vowels that are contained within it. Make sure that both capital vowels and lowercase vowels are counted. Your starter code contains a main function, which asks for user input and outputs the number of vowels. You will need to implement the user input for the string. Sample Runs (user input is italicized and underlined): Enter a phrase: Hello World!Number of vowels: 3 Enter a phrase: PROGRAMMING IS EXCELLENT.Number of vowels: 7 #include <string>#include <iostream>using namespace std; int countVowels(string word); int main(){ string phrase; cout << "Enter a phrase: "; // To do: implement user input cout << "Number of vowels: " << countVowels(phrase) << endl;} // To do: Implement countVowels int countVowels(string word){}

Write a program in Python that asks the user to input an integer and print two integers, root and power, such that 1 < power < 6 and root ** power is equal to the integer entered by the user. If no such pair of integers exists, it should print a message to that effect.
Write a Python function that takes a string as parameter. The string has only the digits 0-10 as characters and its length is divisible by 3. string is not empty. You need to create two new strings. For this, you can use a for loop with a step of 3 (step = 3) to step through the string in blocks of 3 characters. Create the first string where each character is the first character of each block of 3 characters. Create the second string where each 2 characters are the second and third characters of each 3 character block of s.
1. a.Palindromes Complete the function palindrome(String text). Return true if text is a palindrome; if the word is identical forward and backward. Otherwise, return false. Example: palindrome(“racecar”) == true palindrome(“kayaks”) == false See main() for more examples. You can use text.charAt(i) to find the character at index i of text. Use recursion. palindrome() should call itself. No loops allowed. b. Complete the function nestedBrackets(String s). This function should find properly nested brackets within s. Return true if brackets are opened and closed correctly, and false otherwise. Single pairs and nested pairs are valid. For example: z[z]z, [zz[zz]z], [z[[z]zzz]], zzzzz Incorrect pairings and multiple separate pairs are not valid. For example: zz[zz, ]zzz[, [zzz][z], [z[z][z]z] See main() for more examples. nestedBrackets() should call firstIndexOf() and lastIndexOf() to help you solve the problem. Use recursion. nestedBrackets() should call itself. No loops…
A bit shift is a procedure whereby the bits in a bit string are moved to the left or to the right. For example, we can shift the bits in the string 1011 two places to the left to produce the string 1110. Note that the leftmost two bits are wrapped around to the right side of the string in this operation. Define two scripts, shiftLeft.py and shiftRight.py, that expect a bit string as an input. • The script shiftLeft shifts the bits in its input one place to the left, wrapping the leftmost bit to the rightmost position. • The script shiftRight performs the inverse operation. • Each script prints the resulting string. An example of shiftLeft.py input and output is shown below: Enter a string of bits: Hello world! ello world!H An example of shiftRight,py input and output is shown below: Enter a string of bits: Hello world! !Hello world
The same professor writes a program to analyze the chat logs from the various lectures as a partial measure of class participation. Each chat log consists of multiple lines, each of form TIME, NAME, COMMENT, in the order in which they were posted to the chat . The algorithm then sorts all that data - across all the chat logs - in order of student names, and scores each set using a metric based on the number of contributions and their length. [a] What are the various input sizes to consider when analyzing the algorithmic approaches? (One is the number of students in the class, but that is not the only factor.) [b] Which sorting algorithm do you think is best suited for the sorting portion of this algorithm and why? [c] What is the time complexity of the sorting algorithm chosen in step [b] as a function of the various input sizes identified in step [a]? [d] What is the overall time complexity of the chat analysis program as described above?
Write a python function count_matches that, given two strings, counts the number of positions at which the characters are the same. For example, count_matches('conflate', 'banana') returns 2, conflate banana ^ ^ since the n's match at index 1 and the a's match at index 5. The strings to not need to be the same length. The count_matches function does not read input or print output.
