Repeated DNA Sequences

Explore how to detect all repeated 10-character DNA sequences in a string using the sliding window technique. Understand the problem constraints and practice applying a coding pattern focused on substring analysis to solve this problem efficiently.

Statement

A DNA sequence consists of nucleotides represented by the letters ‘A’, ‘C’, ‘G’, and ‘T’ only. For example, “ACGAATTCCG” is a valid DNA sequence.

Given a string, s, that represents a DNA sequence, return all the 10-letter-long sequences (continuous substrings of exactly 10 characters) that appear more than once in s. You can return the output in any order.

Constraints:
