Problem Description

Boudreaux and Thibodeaux are on the road again . . .

"Boudreaux, we have to get this shipment of mudbugs to Baton Rouge by tonight!"

"Don't worry, Thibodeaux, I already checked ahead. There are three underpasses and our 18-wheeler will fit through all of them, so just keep that motor running!"

"We're not going to make it, I say!"

So, which is it: will there be a very messy accident on Interstate 10, or is Thibodeaux just letting the sound of his own wheels drive him crazy?

Input

Input to this problem will consist of a single data set. The data set will be formatted according to the following description.

The data set will consist of a single line containing 3 numbers, separated by single spaces. Each number represents the height of a single underpass in inches. Each number will be between 0 and 300 inclusive.

Output

There will be exactly one line of output. This line will be:

NO CRASH

if the height of the 18-wheeler is less than the height of each of the underpasses, or:

CRASH X

otherwise, where X is the height of the first underpass in the data set that the 18-wheeler is unable to go under (which means its height is less than or equal to the height of the 18-wheeler).
The height of the 18-wheeler is 168 inches.

Sample Input

  
   180 160 170

Sample Output

  
   CRASH 160

C语言AC代码

#include<stdio.h>
int main()
{
    int a,b,c,d=168;
    while(scanf("%d%d%d",&a,&b,&c)!=EOF)
    {
        if(a<d){printf("CRASH %d\n",a);return main();}
        if(b<d){printf("CRASH %d\n",b);return main();}
        if(c<d){printf("CRASH %d\n",c);return main();}
        printf("NO CRASH\n");
    }
    return 0;
}

思路： 168 inches的 18-wheeler要通过三个underpasses，输入三个（0，300）的数，如果三个数字都不能通过就输出 NO CRASH，否则输出CRASH X，X表示第一个通过的underpasses。
