Problem:
Score : 200 points

Problem Statement

We have a grid with N rows and M columns of squares. Initially, all the squares are white.

There is a button attached to each row and each column.
When a button attached to a row is pressed, the colors of all the squares in that row are inverted; that is, white squares become black and vice versa.
When a button attached to a column is pressed, the colors of all the squares in that column are inverted.

Takahashi can freely press the buttons any number of times. Determine whether he can have exactly K black squares in the grid.

Constraints

1 \leq N,M \leq 1000

0 \leq K \leq NM

Input

Input is given from Standard Input in the following format:

N M K

Output

If Takahashi can have exactly K black squares in the grid, print Yes; otherwise, print No.

Sample Input 1

2 2 2

Sample Output 1

Yes

Press the buttons in the order of the first row, the first column.

Sample Input 2

2 2 1

Sample Output 2

No

Sample Input 3

3 5 8

Sample Output 3

Yes

Press the buttons in the order of the first column, third column, second row, fifth column.

Sample Input 4

7 9 20

Sample Output 4

No

#include <iostream>

using namespace std;
int main() {
	int n, m, k;
	cin >> n >> m >> k;
	int a[1005][1005];

	int x = 0;
	int y = 0;
	for(int i=1;i<n+1;i++){
		for(int j=1;j<m+1;j++){
			a[i][j] = j*m+i*n-2*(i*j);
			if(a[i][j]==k){
				ans = "Yes";
				x = i;
				y = j;
			}
		}
	}
	cout << ans <<  endl;
	cout << x << y << endl;
	return 0;
