Challenge: Find Two Numbers That Add up to k—Hashing

Explore how to find two numbers in an integer list that add up to a target value using hashing methods. This lesson guides you through implementing efficient C++ code to solve this common interview problem while understanding the fundamentals of hash tables and their practical applications.

We'll cover the following...

Statement

Given a list of integers, nums, and an integer target, k, find two numbers in the list that sum up to the target k.

There is exactly one solution for each input, and each element of the list can only be used once in the solution. The order of the returned elements does not matter.

Constraints:

  • 2≤2 \leq nums.length ...
