Repeated DNA Sequences

Explore how to solve the problem of finding repeated 10-letter-long DNA sequences within a given string. Understand the sliding window technique for efficient data processing in strings, and implement your solution using a hands-on coding environment.

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:
