Two Sum
Problem:
Given an array of integers
numsand an integertarget, return indices of the two numbers such that they add up to target.Approach:
Use a hash map (dictionary) to store visited numbers and their indices. For each element, check if the complement (target - current number) exists in the map. If yes, return the indices.
Time Complexity: O(n)
Space Complexity: O(n)
Difficulty Level: Easy
