# Statement

Write a function that takes a string, `s`, as an input and determines whether or not it is a palindrome.

> **Note**: A **palindrome** is a word, phrase, or sequence of characters that reads the same backward as forward.


**Constraints:**

- $1 \leq$ `s.length` $\leq 2 \times 10^5$
- The string `s` will not contain any white space and will only consist of ASCII characters(digits and letters).
