Two Sum - LeetCode Problem Explained
In this video, we tackle the popular "Two Sum" problem from LeetCode. This beginner-friendly DSA (Data Structures and Algorithms) problem tests your ability to efficiently find indices of two numbers in an array that add up to a given target.
We’ll break down the problem with clear examples:
Example 1:
Input: nums = [2, 7, 11, 15], target = 9
Output: [0, 1]
Explanation: nums[0] + nums[1] = 2 + 7 = 9
Example 2:
Input: nums = [3, 2, 4], target = 6
Output: [1, 2]
Explanation: nums[1] + nums[2] = 2 + 4 = 6
We’ll also cover key constraints, including edge cases and optimal solutions, using both brute force and efficient approaches like hash maps for O(n) complexity.
By the end of this video, you’ll have a clear understanding of the problem, how to solve it efficiently, and how to apply these techniques to similar problems.
