q$3$ You are required to write a C$++$ program that performs two tasks on a given input string. The first task is to count how many letters in the string are repeated and how many times each of them is repeated. The second task is to check if the input string is a palindrome using vectors.Complete the following steps:$1.$Repeated Letters Count:Implement a function to count how many letters in the input string are repeated and how many times each of them is repeated. Print the results$\mathrm{.}2.$Palindrome Check Using Vectors:Implement a function to check if the input string is a palindrome using vectors. A palindrome is a string that reads the same backward as forward. Print whether the string is a palindrome or not.$($DO NOT USE AI PLEASE$)$
