在vs2019上运行都是对的，但提交没有一个是对的，求大佬帮忙看看，救救可怜的孩子吧！！```c

include<iostream>

using namespace std; int a[3000]; void cheng(int a, int c) { int jw = 0; for (int i = 0; i < 3000; i++) { a[i] = a[i] c + jw; jw = a[i] / 10; a[i] = a[i] % 10; } } int main() { int t; cin >> t; int d[10]; int d1 = 0; for (int i = 0; i < t; i++) { int n, b; cin >> n >>b; a[1] = 1; for (int j = 1; j <= n; j++) { cheng(a, j); } int num = 0; int k; for (int j = 3000; j > 0; j--) { if (a[j] != 0) { k = j; break; } } for (int j = 1; j <= k; j++) { if (a[j] == b) { num++; } } d[d1] = num; d1++; } for (int i = 0; i < d1; i++) { cout << d[i] << endl; } return 0; }
