  Medium
  
  URL: https://leetcode.com/problems/repeated-dna-sequences/
  
  All DNA is composed of a series of nucleotides abbreviated as A, C, G, and T,
  for example: "ACGAATTCCG". When studying DNA, it is sometimes useful to identify
  repeated sequences within the DNA.
  
  Write a function to find all the 10-letter-long sequences (substrings) that occur more
  than once in a DNA molecule.
  
  Example:
  Input: s = "AAAAACCCCCAAAAACCCCCCAAAAAGGGTTT"
  Output: ["AAAAACCCCC", "CCCCCAAAAA"]
