    459 - Repeated Substring Pattern.

    Easy

    Given a string s, check if it can be constructed by taking a substring of it and appending multiple copies of the substring together.

    Example 1:

    Input: s = "abab"

    Output: true

    Explanation: It is the substring "ab" twice.

    Example 2:

    Input: s = "aba"

    Output: false

    Example 3:

    Input: s = "abcabcabcabc"

    Output: true

    Explanation: It is the substring "abc" four times or the substring "abcabc" twice.

    Constraints:

    • <code>1 <= s.length <= 10<sup>4</sup></code>

    • s consists of lowercase English letters.
