With the help of the given rules and clues, you have to figure out which box contains which digit.
The rules are:
1: No row or column can have the same digit appearing more than once.

And the clues are:
1. The empty spaces are B3, C2, C4 and D4.
2. The sum of digits in row A equal 11.
3. The sum of digits in row B equal 22.
4. The sum of digits in row C equal 12.
