Check If String Is a Rotation of Another

Given two strings `s1` and `s2`, return `true` if `s2` is a rotation of `s1`, or `false` otherwise. A rotation of a string can be formed by moving characters from the front of the string to the back any number of times. ### Constraints - `1 <= s1.length, s2.length <= 10^5` - `s1` and `s2` consist of lowercase English letters. ### Input Format Two space-separated strings `s1` and `s2` on a single line. ### Output Format Print `true` if `s2` is a rotation of `s1`, otherwise `false`.
