13, 14, 15, 16 timed out.

Any clue on this ??

include

int X, Y, order, odr, limit, bfound= 0;

int f[50];

void calAns(int idx, int x, int y);

void init();

void init()

for(i = 0; i<50; i++)

    f[i] = 0;

}

scanf("%d",&T);

for(tc = 1; tc<= T; tc++)

{

    init();

    scanf("%d",&X);

    scanf("%d",&Y);

    scanf("%d",&order);

    limit = X + Y;

    calAns(0, 0, 0);

}

return 0;

}
