Solution: Find Two Numbers That Add Up to K
Explore how to find two numbers in a Python list that add up to a given target number. Understand and implement three approaches: a naive nested loop method, an efficient two-pointer technique after sorting, and a binary search strategy. Learn the time and space complexities of each to better optimize your solutions.
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:
nums.lengthnums[i]...
