北大ACM 1006题 wrong answer

#include <stdio.h>
void Triple(int p, int e, int i, int d)
{
int count=1;
int r,x;
int flag = 0;
while(1)
{
scanf("%d%d%d%d", &p, &e, &i, &d);
if(-1 == p && -1 == e && -1 == i && -1 == d)
break;

for(r = 1; r < 21252; r++)
{
if(!((23*r + p - e)%28) && !((23*r + p - i)%33))
{
flag = 1;
break;
}
}
if(!flag)
{
printf("Case %d: the next triple peak occurs in 21252\
days.\n", count);
}
else
{
x = 23*r + p - d;
printf("Case %d: the next triple peak occurs in\
%d days.\n", count, x);
}
count++;
}
}
int main()
{
int p, e, i, d;
Triple(p, e, i, d);
return 0;
}
