Paulinho have in your hands a little problem. The teacher asked him to make a program to verify from two integer numbers A and B, if B  corresponds to the last digit of A.

For each test case, print a message informing if the second number fit ("encaixa" in portuguese) or didn't fit ("nao encaixa") in the first number.
