Problem: Repeated DNA Sequences
med
30 min
Explore how to detect repeated 10-letter sequences in DNA strings using the sliding window approach. This lesson helps you understand substring identification and efficient string manipulation to solve pattern recognition problems common in coding interviews.
Statement
A DNA sequence consists of a series of nucleotides, each represented by one of the characters 'A', 'C', 'G', or 'T'.
Given a string s representing a DNA sequence, find and return all s. The result may be returned in any order.
Constraints:
s.lengths[i]is one of'A','C','G', or'T'
Examples
