Sqrt(x)
(https://leetcode.com/problems/sqrtx/)
Given a non-negative integer x, return the square root of x rounded down to the nearest integer. The returned integer should be non-negative as well.
You must not use any built-in exponent function or operator.

Valid Palindrome
(https://leetcode.com/problems/valid-palindrome/)
A phrase is a palindrome if, after converting all uppercase letters into lowercase letters and removing all non-alphanumeric characters, it reads the same forward and backward. Alphanumeric characters include letters and numbers.

Given a string s, return true if it is a palindrome, or false otherwise.

These questions are excellent for practice. I will solve all of them during my practice sessions.
