题意:   有一个1→n的排列形成的数列,我们要用最少的操作次数把这个数列从小到大排序,每次操作都是把一个数放到整个数列的最前面. 思路:        首先最大的数n是不用操作的(其他数操作好了,n自然在最后面了).先找到数n的位置,在n之前找n-1,若没找到n-1,则n-1需要操作,所有小于n-1的数均需要操作:若找到了n-1,再接着往前依次找n-2,n-3,...假如数k找不到了,那就是至少需要k次操作. 复杂度O(n). #pragma comment(linker, "/STACK:1…
题意: 有n本书,编号为1~n,现在书的顺序乱了,要求恢复成有序的样子,每次只能抽出其中一本并插到最前面,问最少需要多少抽几次? 思路: 如果pos[i]放的不是书i的话,则书i的右边所有的书都必须抽出来.抽出来的书必定可以回到它最终的位置上,即每本书最多抽出来1次,可以想象抽出来后直接扔掉,在剩下的书中找到一个有序,且最后一个元素为n,且等差为1的序列{...n-2,n-1,n}. //#include <bits/stdc++.h> #include <iostream> #i…
