巧妙之处在于当人数是奇数时,其选择方案是第一个人尽量靠左选,以后编号为偶数的人尽量靠左选,编号为奇数的人尽量靠右选。然后二分枚举可能的礼物数量,看最后是否满足题目要求——第一个人和最后一个人不选重。细节问题总结:重定义全局变量会导致错误,切不好检查出来,应谨慎。#include #include #include usingnamespacestd; constintmaxn=100010; i

题意:有n个人围成一个圈,其中第i个人想要ri个不同的礼物。求最少需要多少种礼物,使得相邻的人的礼物都不相同。思路:这是大白上面的一道贪心题目。想法挺好的。首先如果n为偶数时,只要找出相邻两个人的r值最大,就是所需的最少的礼物数量。如果为奇数时,那情况就不一样了,因为当第1个和第n个都是奇数,按照上面的方法,他们的礼物种类是一样的,就不符合题意。那么我们可以按照第一个人所需要的礼物数量为基准划分区
