题意:给定两个字符串,你可以替换或者置换,替换是指可以将相同的字母替换为任意一个字母,而置换是指将字母替换为下一个,如A替换B,B替换为C,,,Z替换为A.你需要判断是否可以通过一系列操作使两个字符串相等. 思路:既然可以替换和置换,那么我们就可以用两个数组统计两个字符串中各个字母出现的次数,因为可以随意替换,随意我们只需要将两个数组排序,然后比较两个数组是否相等即可. 代码: #include<iostream> #include<cstdio> #include<cstr…

这题就真的想刘汝佳说的那样,真的需要想象力,一开始还不明白一一映射是什么意思,到底是有顺序的映射?还是没顺序的映射? 答案是没顺序的映射,只要与26个字母一一映射就行 下面给出代码 //Uva1339 //Ancient Cipher //easy #include<cstdio> #include<cstring> #include<algorithm> using namespace std; int main() { freopen("Ancient.i…

UVa 1339 题目大意:给定两个长度相同且不超过100个字符的字符串,判断能否把其中一个字符串重排后,然后对26个字母一一做一个映射,使得两个字符串相同 解题思路:字母可以重排,那么次序便不重要,可以分别统计两个字符串中的各个字母出现的次数,得到两个cnt[26]数组, 又由于可以进行映射,则可以直接对两个数组进行排序后判断是否相等(相当于原来相等的值的两个地方做映射) /* UVa 1339 Ancient Cipher --- 水题 */ #include <cstdio> #incl…

2017-08-31 20:11:39 writer:pprp 一开始说好这个是个水题,就按照水题的想法来看,唉~ 最后还是懵逼了,感觉太复杂了,一开始想要排序两串字符,然后移动之类的,但是看了看 好像没有什么规律... 然后就去膜大神code了 其实转换了一个思路,对两个字符串分别统计每个的个数, 然后分别排序,如果每个个数都可以对的上就说明可以通过两个操作得到 代码如下: /* @theme:poj 2159 ancient cipher @writer:pprp @declare: @be…
