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 haveexactlyone solution, and you may not use thesameelement twice. Example: Given nums = [2, 7, 11, 15], target = 9, Because nums[0] +...
基于常见的实践，甚至可以将print语句放在方法之外，在main.
