Two Sum - Swift (Leetcode)

In this video I go over how to do 1. Two Sum - Leetcode in the Swift programming language. Two sum is an Easy rated difficulty starter problem that mostly everyone does when getting their start in technical interviewing.

Time Complexity is O(n) because we only need to make one pass through the input array and lookup in the dictionary is also O(n).

Space Complexity is O(n) worst case because we may need to add all the contents of the input array.
