TWO SUM LEETCODE JAVA SOLUTION / LEETCODE PROBLEMS AND SOLUTION / JAVA CODING SERIES
Welcome to this YouTube tutorial on solving the Two Sum problem on LeetCode using Java and the hashmap approach. In this problem, you are given an array of integers, 'nums', and an integer target. Your task is to find two numbers in the array that add up to the target and return their indices. You can assume that each input will have exactly one solution, and you cannot use the same element twice. The order of the indices in the output does not matter.

In this tutorial, we will guide you through the step-by-step process of solving this problem efficiently using a hashmap. We will explain the problem statement and provide intuitive examples to help you understand the concept.

Example 1:
Input: nums = [2,7,11,15], target = 9
Output: [0,1]
Explanation: The numbers at indices 0 and 1, i.e., nums[0] + nums[1], sum up to the target value (9).

Example 2:
Input: nums = [3,2,4], target = 6
Output: [1,2]

To efficiently solve the Two Sum problem, we will utilize a hashmap to store the elements of the array and their corresponding indices. We will demonstrate how to implement the solution using Java code, explaining each step along the way.

Whether you're preparing for coding interviews or looking to improve your algorithmic problem-solving skills, this tutorial is perfect for you. Watch the full video to grasp the concept of using a hashmap to solve the Two Sum problem on LeetCode.
