Field Should Not Be Empty 这道题目的思想非常新 首先我们按照比较传统的想法,考虑交换两个位置i和j能带来什么影响 然后这就是这道题目的精华所在了,我们考虑影响的时候,没有必要去精确每一个位置的两个信息(左边更大的数的个数和右边更小的数的个数)怎么样变化,而是只用考虑这一次交换会让答案增大多少(其实...
首先特判一下∀i,pi=i的情况,输出n−2,不难发现剩下的情况必定需要交换两个数。 首先考虑设ai表示i左边比pi大的数的个数与i右边比pi小的数的个数之和,a数组可以用树状数组简单求出。 我们发现此时的f(p)值即为满足ai=0的i的个数。 考虑若交换i,j,此时的a数组会如何变化。
