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 <bits/stdc++.h>

using namespace std;
using ll = long long;
using pii = pair<int,int>;

int main() {
	// freopen("in.txt","r",stdin);
	int n,m,k;
	cin >> n >> m >> k;
	for (int a = 0; a <= n; ++a)
		for (int b = 0; b <= m; ++b)
			if (a*m + b*n - 2*a*b == k) {
				cout << "Yes" << endl;
				return 0;
			}
	cout << "No" << endl;
