时间限制: 1 Sec 内存限制: 128 MB

题目描述

A common typing error is to place the hands on the keyboard one row to the right of the correct position. So "Q" is typed as "W" and "J" is typed as "K" and so on. You are to decode a message typed in this manner.

输入

Input consists of several lines of text. Each line may contain digits, spaces, upper case letters (except Q, A, Z), or punctuation shown above [except back-quote (`)]. Keys labelled with words [Tab, BackSp, Control, etc.] are not represented in the input.

输出

You are to replace each letter or punctuation symbol by the one immediately to its left on the QWERTY keyboard shown above. Spaces in the input should be echoed in the output.

样例输入

O S, GOMR YPFSU/

样例输出

I AM FINE TODAY.

把所有的字符按键盘排列从左到右保存在数组中，当输入字符为非空格时找到这个元素的数组下标，输出该元素的前一位；否则，原样输出空格；往复循环，直至文件结束。

<span style="font-size:18px;">#include<cstdio>#include<string.h>using namespace std;int main(){    int i,c ;    char s[]="`1234567890-=QWERTYUIOP[]\ASDFGHJKL;'ZXCVBNM,./";    while((c=getchar())!=EOF)    {        for(i=1;s[i]&&c!=s[i];i++);             //“；”找到符合条件的元素的位置            if(s[i])<span style="white-space:pre"></span>//空格原样输出                putchar (s[i-1]);            else                putchar (c); }<span style="white-space:pre"></span>return 0;}</span>
