Problem Statement

X and A are integers between 0 and 9 (inclusive).

If X is less than A, print 0; if X is not less than A, print 10.

Constraints

0 \leq X, A \leq 9

All values in input are integers.

Input

Input is given from Standard Input in the following format:

X A

Output

If X is less than A, print 0; if X is not less than A, print 10.

Sample Input 1

3 5

Sample Output 1

0

3 is less than 5, so we should print 0.

Sample Input 2

7 5

Sample Output 2

10

7 is not less than 5, so we should print 10.

Sample Input 3

6 6

Sample Output 3

10

6 is not less than 6, so we should print 10.

Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <stdio.h>
#include <stdlib.h>

int main(void) {
    long long int n, k;
    long long int *a;
    long long int sum = 0;
    long long int ans;

    scanf("%lld%lld", &n, &k);

    a = calloc(n, sizeof(long long int));

    long int i, j;

    for (i = 0; i < n; i++) {
        scanf("%lld", &a[i]);
    }

    i = 0;

    while (sum < k && i < n) {
        sum += a[i++];
    }

    if (i == n)
        printf("0\n");

    else {
        ans = n - i + 1;

        for (j = 1; j < n - 1; j++) {
            sum -= a[j-1];
            while (sum < k && i < n) {
                sum += a[i++];
            }
            ans += n - i + 1;
        }

        printf("%lld\n", ans);
    }

    return 0;
}
