本文介绍了一种解决常见键盘输入错误的方法，通过将输入的每个字符替换为QWERTY键盘上其左侧的字符来纠正偏移的打字错误。文章提供了一个简单的C++程序实现，并附带示例输入输出。

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.

Input

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.

Output

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

Sample Input

O S, GOMR YPFSU/

Sample Output

I AM FINE TODAY.

这道题其实是常量数组的一个应用

 1 #include<iostream>
 2 #include<cstdio>
 3 #include<cstring>
 4 #include<cmath>
 5 #include<algorithm>
 6 using namespace std;
 7 char s[]="`1234567890-=QWERTYUIOP[]\\ASDFGHJKL;'ZXCVBNM,./";
 8 int main()
 9 {
10     int i,c;
11     while((c=getchar())!=EOF)
12     {
13         for(i=1;s[i]&&s[i]!=c;i++);
14         if(s[i]) putchar(s[i-1]);
15         else putchar(c);
16     }
17     return 0;
18 }
