Find two numbers that sum to target

Last updated: Mar 29, 2026

Quick Overview

This question evaluates a candidate's competency in array manipulation, index reasoning, and efficient algorithmic techniques for pair-sum problems. It is commonly asked in technical interviews to measure problem-solving ability, understanding of algorithmic complexity, and practical implementation skills within the Coding & Algorithms domain, focusing on practical application rather than purely conceptual theory.

Problem

You are given an integer array nums (length n) and an integer target.

Return the indices (i, j) such that:

i != j
nums[i] + nums[j] == target

Assume:

Exactly one valid pair exists.
You may return the indices in any order.

Example

Input: nums = [2, 7, 11, 15] , target = 9
Output: (0, 1)
