本文介绍了一种键盘输入错误的解码方法，当用户的手指放置在一排右侧的位置进行打字时，如将Q误打为W等，文章提供了一个程序来纠正这类错误，并附带了具体的实现代码。

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 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. 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/

Output for Sample Input

I AM FINE TODAY.

#define RUN
#ifdef RUN


#include <stdio.h>
char *s = "`1234567890-=QWERTYUIOP[]\\ASDFGHJKL;'ZXCVBNM,./";
int main(){
	int i,c;
	while ((c = getchar()) != EOF) {

		for (i=1; s[i] && s[i]!=c; i++);

		if (s[i])
			putchar(s[i-1]);
		else
			putchar(c);
	}
	return 0;
}



#endif
