题目连接:Equalize the Remainders 题意:n个数字,对m取余有m种情况,使得每种情况的个数都为n/m个(保证n%m=0),最少需要操作多少次? 每次操作可以把某个数字+1.输出最少操作次数,和操作后的序列(可以输出任意一种). 题解:用一个set来维护所有余数x(当前余数为x的数个数没凑够n/m个),对于每个数假设这个数的余数为t,当余数为t的数个数没凑够n/m时那这个数就不需要改变,如果已经凑够了,那就在set中找到第一个大于等于t的数(注意这里t可能比set中最大数的还…

刷题备忘录,for bug-free 招行面试题--求无序数组最长连续序列的长度,这里连续指的是值连续--间隔为1,并不是数值的位置连续 问题: 给出一个未排序的整数数组,找出最长的连续元素序列的长度. 如: 给出[100, 4, 200, 1, 3, 2], 最长的连续元素序列是[1, 2, 3, 4].返回它的长度:4. 你的算法必须有O(n)的时间复杂度 . 解法: 初始思路 要找连续的元素,第一反应一般是先把数组排序.但悲剧的是题目中明确要求了O(n)的时间复杂度,要做一次排序,是不能达…
