    187 - Repeated DNA Sequences\.

    Medium

    The DNA sequence is composed of a series of nucleotides abbreviated as 'A', 'C', 'G', and 'T'.

    • For example, "ACGAATTCCG" is a DNA sequence.

    When studying DNA , it is useful to identify repeated sequences within the DNA.

    Given a string s that represents a DNA sequence , return all the 10\-letter-long sequences (substrings) that occur more than once in a DNA molecule. You may return the answer in any order.

    Example 1:

    Input: s = "AAAAACCCCCAAAAACCCCCCAAAAAGGGTTT"

    Output: "AAAAACCCCC","CCCCCAAAAA"

    Example 2:

    Input: s = "AAAAAAAAAAAAA"

    Output: "AAAAAAAAAA"

    Constraints:

    • <code>1 <= s.length <= 10<sup>5</sup></code>

    • s[i] is either 'A', 'C', 'G', or 'T'.
