Problem Statement for Day3

Given an integer x, return true if x is a palindrome integer.

An integer is a palindrome when it reads the same backward as forward.

Approach:

The first step is to create a base case which is when the length of the integer is equal to 1. When this case is encountered, the function returns true because a single-digit integer is a palindrome.

When the integer isn't a single digit integer, we initialized a for loop with a range equal to half the length of the integer, this is because we would be carrying out a comparison of the ends of the integer and would only need to loop n/2 times(where n is the size of the integer).

On each iteration, we compare the ends using this statement x[i] == x[~i] When the loop is exited successfully with all comparisons evaluating to true, we return True confirming that the integer is indeed a palindrome.

if a comparison evaluates to False, the loop ends and returns False.
