Content 给你 \(26\) 个字母的映射(都是小写,大写的映射方式相同),再给你一个字符串 \(s\),求它的映射结果(如果有非字母的字符保持不变). 数据范围:\(1\leqslant |s|\leqslant 1000\). Solution 强大的 \(\texttt{map}\) 正好能够为我们做出映射的功能,我们直接存储每个字母的映射再直接将原字符串映射即可. Code #include <cstdio> #include <algorithm> #include…

作者:zifeiy 标签:状压DP,子集划分DP 题目链接:https://codeforces.com/contest/1238/problem/E 题目大意: 给你一个长度为 \(n(n \le 10^5)\) 的字符串s和 \(m(m \le 20)\) ,这个字符串由前 \(m\) 个小写字母组成. 现在你要找一个前 \(m\) 个字符的一个排列p,在这个排列p的基础上生成字符串s,并计算总代价. 代价的计算过程是: 比如我现在已经生成了字符串s的前i个字符 \(s_{1..i}\) ,…

题目链接:http://codeforces.com/contest/831/problem/B 题目意思:给出两个长度为26,由小写字母组成的字符串s1和s2,对于给出的第三个字符串s3,写出对应s1中字符在s2中的映射.如果是大写字母,最终输出也是大写字母:如果是数字,保留不做任何更改 题目解析:这里主要用了map<int, int> 来记录s1中的key,value 值,key是字母经处理后的对应数字形式,value是字母对应的位置 调试得比较久,用 map用得少,不熟悉哇~~   &g…

Introduction The system locale specifies the language settings of system services and user interfaces. The keyboard layout settings control the layout used on the text console and graphical user interfaces. These settings can be made by modifying the…

Using keyboard shortcuts To use a keyboard shortcut, press a modifier key at the same time as a character key. For example, pressing the Command key (it has a ⌘ symbol) and then the "c" key copies whatever is currently selected to the Clipboard.…
