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：

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.

O S, GOMR YPFSU/

样例输出：

I AM FINE TODAY.

char keyboard[]={'`','1','2','3','4','5','6','7','8','9','0','-','=','Q','W','E','R','T','Y','U',
'I','O','P','[',']','\\','A','S','D','F','G','H','J','K','L',';','\'','Z','X','C','V','B','N','M',',','.','/'};

int main()
{
    char string[1000];
    int i,j;

    while(gets(string))
    {
        for(i = 0;i < strlen(string);i++){
            if(string[i] == ' '){
                printf(" ");
            }
            else{
                for(j = 0;j < strlen(keyboard);j++){
                    if(string[i] == keyboard[j]){
                        printf("%c",keyboard[j-1]);
                        break;
                    }
                }
            }
        }
        printf("\n");
