If found in the HashMap, we will print the indices else we will put the element in the HashMap.

Follow the steps below to solve the given **problem**: Initialize the count variable with 0 which stores the result. Iterate arr and if the **sum** of ith and jth [i + 1..n - 1] element is equal to **sum** i.e. arr [i] + arr [j] == **sum**, then increment the count variable. Return the count. Below is the implementation of the above approach. C++ C Java Python3. 1. **Two** **Sum** Easy Given an array of integers nums and an integer target, return indices of the **two** numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may not use the same element twice. You can return the answer in any order. Example 1:. Now, let's take a look at the different solutions to the **two-sum** **problem** using Python3. First Approach def twoSum(self, nums: List [int], target: int) -> List[int]: for i in range (len (nums)): for j in range (i + 1, len (nums)): if nums [i] + nums [j] == target: return [i,j] The solution seems simple enough, right?.
