Не проходит Тест 3.
из темы http://acm.timus.ru/forum/thread.aspx?id=40287&upd=636486286708718852 взял условие, на компьютере все в порядке, отсылаю в тимус: Time limit exceeded

#include <stdio.h>
int mas[99999];
long int i, n;
unsigned long int a, cou = 0, s = 0;
int main()
{
    scanf("%d", &n);
    for (i = 0; i < n; i++){
        scanf("%u", &a);
        cou = 0; s = 1;
        while(s < a){
            cou++;
            s = s + cou;
        }
        if (a == s){
            mas[i] = 1;
        } else {
            mas[i] = 0;
        }

    }
    for (i = 0; i < n; i++){
        printf("%d ", mas[i]);
    }
    return 0;
}

Подскажите пожалуйста что не так.

your mass[99999] must be 'long long'. Because Ki <= (1 << 31) - 1;

Study the consistent pattern in a given sequence (1101001000...) and use the quadratic equation. Luck!
