Solution: Find Two Numbers That Add up to k—Hashing
Explore how to implement a solution in C++ that finds two numbers in an array adding up to a specific target using hashing methods. Understand both unordered_map and unordered_set approaches along with their time and space complexity, enabling you to write efficient code for interview problems.
Statement
Given an array of integers nums and an integer target, k, find two numbers in the array that sum up to the target k.
There is exactly one solution for each input, and each element of the array can only be used once in the solution. The order of the returned elements does not matter.
Constraints:
nums.length...
