I’m practising my programming skills on LeetCode.
This demo implemented the Two Sum:
Given an array of integers, return indices of the two numbers such that they add up to a specific target.
You may assume that each input would have exactly one solution, and you may not use the same element twice.
Given nums = [2, 7, 11, 15], target = 9,from LeetCode No.1 problem
Because nums + nums = 2 + 7 = 9, return [0, 1].
You can choose your favourite language to solve the problems.
