Solution: Find Two Numbers That Add Up to K
Explore methods to find two numbers that sum to a specified target in an array. Learn the naive nested loop approach, the two-pointer technique after sorting, and binary search optimization. Understand the time and space complexity of each solution to improve problem-solving for coding interviews.
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.lengthnums[i]...
