Solution: 3Sum
Explore the two-pointer technique to solve the 3Sum problem by identifying all unique triplets in an integer array that sum to zero. Learn to sort arrays, effectively move pointers, and skip duplicates. This lesson teaches how to implement an efficient O(n^2) time complexity solution useful for coding interviews at top tech companies.
