Problem:
Print a Rectangle

Draw a rectangle which has a height of H cm and a width of W cm. Draw a 1-cm square by single '#'.

Input

The input consists of multiple datasets. Each dataset consists of two integers H and W separated by a single space.

The input ends with two 0 (when both H and W are zero).

Output

For each dataset, print the rectangle made of H × W '#'.

Print a blank line after each dataset.

Constraints

1 ≤ H ≤ 300

1 ≤ W ≤ 300

Solution in C++ (judge verdict: Accepted)

#include <iostream>

using namespace std;

int H, W;

void solve() {
    if(H == 0 && W == 0) return;
    for(int i = 0; i < H; i++) {
        for(int j = 0; j < W; j++) {
            cout << "#" << flush;
        }
        cout << endl;
    }
    cout << endl;
}

int main() {
    do {
        cin >> H >> W;
        solve();
    }while(H != 0 || W != 0);
}
