Associate each letter with the correct number, given that:

• If A is 1, then B is not 3.
• If B is not 1, then D is 4.
• If B is 1, then C is 4.
• If C is 3, then D is not 2.
• If C is not 2, then D is 2.
• If D is 3, then A is not 4.

The following satisfy all of the bullets but may not be the only solution.
A can be any number
B=1, C=4, D=2

If they are supposed to be different numbers from 1 to 4 then A=3
