题目描述: 从1~n中,随便的拿出一个数字,你来猜测。 提示 提供一个guess(int num)的api,针对猜测的数字,返回三个数值。0,-1,1 0;猜中返回num-1:比猜测的数值小1:比猜测的数值大 例如: n = 10, I pick 6. Return 6. 原文描述: We are playing the Guess Game. The game is as fo
题目: Given an array of integers, find out whether there are two distinct indices i and j in the array such that the difference between nums[i] and nums[j] is at most t and the difference between i an
This way 题意: 给你n个数,让他们两两配对,要求每个数最多只有一个数与它匹配,并且两个数的差>=z,问你最大有多少对数可以匹配 题解: 非常敢单,但是有一些细节问题要注意一下。 首先我是先排序,再用lower_bound来做,但是lower_bound的时候要注意每个数只能找后半部分的数,因为找前面的数会出现一个问题:假设有1,10,15,20这四个数,z是9,那么如果lower
