Two Sum - Leetcode 1 - HashMap - Python- Explain
Leetcode link: https://leetcode.com/problems/two-sum/ To efficiently solve the Two Sum problem, we'll utilize a hashmap in Python. Here's the step-by-step breakdown of the solution: Initialize an empty hashmap to store the complement values. Iterate through the input array. For each number, calculate its complement by subtracting it from the target. Check if the complement value exists in the hashmap. If it does, return the indices of the current number and its complement. If not, store the current number and its index in the hashmap. If no solution is found after iterating through the entire array, return an empty list. #python #hashmap #CodingInterview
