Solution: Find Two Numbers That Add Up to K
Learn to identify two numbers in an integer list that add up to a specified target. Explore three approaches: a naive nested loop, a two-pointer method after sorting, and a binary search technique. Understand their time and space complexities to choose the best solution for interview problems.
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.
