[UVa]10550:Combination Lock

此題感覺很簡單，
但是請你一定要想一想，
如果你順時針轉數字鎖的時候，
數字卻是會逆時針轉動的！= =
我被這個騙了三次......

[C](0.016)

	#include<stdio.h>
	int main()
	{
	int start, pw1, pw2, pw3;
	while( scanf( "%d%d%d%d", &start, &pw1, &pw2, &pw3 ) != EOF )
	{
	if( start == 0 && pw1 == 0 && pw2 == 0 && pw3 == 0)
	break;
	int angle = 1080;
	angle += ( start - pw1 < 0 )? (start - pw1 + 40) * 9 : (start - pw1) * 9;
	angle += ( pw2 - pw1 < 0 )? (pw2 - pw1 + 40) * 9 : (pw2 - pw1) * 9;
	angle += ( pw2 - pw3 < 0 )? (pw2 - pw3 + 40) * 9 : (pw2 - pw3) * 9;
	printf( "%d\n", angle );
	}
	return 0;
	}
