LeetCode Two Sum Explained: Find Indices of Numbers Adding Up to Target
Learn how to solve the LeetCode Two Sum problem efficiently. This tutorial covers step-by-step solutions in C++.
"Welcome to our LeetCode problem-solving series! In this video, we tackle the popular ‘Two Sum’ problem. Given an array of integers nums and an integer target, we return the indices of the two numbers that add up to the target. This problem is a staple in coding interviews and a great way to improve your problem-solving skills.
🔍 Problem Statement:
Given an array of integers nums and an integer target, return the indices of the two numbers such that they add up to the target. Each input will have exactly one solution, and you may not use the same element twice. You can return the answer in any order.
📊 Example 1:
Input: nums = [2,7,11,15], target = 9
Output: [0,1]
📊 Example 2:
Input: nums = [3,2,4], target = 6
Output: [1,2]
📊 Example 3:
Input: nums = [3,3], target = 6
Output: [0,1]
