题意:给定一个手机,然后一共有 n 个app,告诉你每个屏幕最多放 k 个,现在要你运行 m 个app,每次都从第一个屏幕开始滑动,每运行一个,它就和前一个交换位置,第一个就不换了,现在问你要滑动多少次. 析:这个题,没什么算法,就是模拟呗,不过要注意时间,不能TLE,所以我们就得提前把所有的位置都存下来,让查找的时间变成 O(1),否则就会超时,可以用两个数组,也可以用map,一个存编号,一个存位置, 然后运行完后再交换就行了. 代码如下: #include <iostream> #incl…

A. Vitaly and Strings 题意:两个字符串s,t,是否存在满足:s < r < t 的r字符串 字符转处理:字典序排序 很巧妙的方法,因为s < t,只要找比t字典序稍微小一点的和s比较就行了 具体方法和数字减1相类似,从"个位"减1,如果是0,从前面借1 !strcmp (t, s):如果t < s 或者 t > s (不可能)则输出,t == s 则输出NO #include <cstdio> #include <i…
