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.

Create a function that will test if a string is a valid PIN or not via a regular expression. A valid PIN has: Exactly 4 or 6 characters. Only numeric characters (0-9). • No whitespace. Examples validate("121317") → true validate("1234") → true validate("45135") → false validate("89abc1") → false validate("900876") → true validate(" 4983") false

In c++ and without the use of vectors, please. Thanks very much! A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name. Define and call the following function. The return value of FindContact is the index of the contact with the provided contact name. If the name is not found, the function should return -1 This function should use binary search. Modify the algorithm to output the count of how many comparisons using == with the contactName were performed during the search, before it returns the index (or -1). int FindContact(ContactInfo contacts[], int size, string contactName) Ex: If the input is: 3…

Given a string with duplicate characters in it. Write a program to generate a list that only contains the duplicate characters. In other words, your new list should contain the characters which appear more than once. Suggested Approach Used two nested for loops. The first for loop iterates from 0 to range(len(input_str)). The second for loop iterates from first_loop_index + 1 to range(len(input_str)). The reason you want to start at first_loop_index + 1 in the nested inner loop is that the outer loop already checks the current character. In the nested inner loop, you want to check the remaining characters in the input string. If the current character of the outer loop matches the character of the nested loop AND the character is not already IN the duplicate list, append it to the list nhantran Sample Output 1 List of duplicate chars: ['n', 'a'] Sample Input 2 pneumonoultramicroscopicsilicovolcanoconiosis Sample Output 2 List of duplicate chars: ['p', 'n', 'u', 'm', 'o', 'l', 'r', 'a',…
