Find the difference of two sets $A = \{a_0, a_1, ..., a_{n-1}\}$ and $B = \{b_0, b_1, ..., b_{m-1}\}$, $A - B$.
The input is given in the following format.
$n$ $a_0 \; a_1 \; ... \; a_{n-1}$ $m$ $b_0 \; b_1 \; ... \; b_{m-1}$
Elements in $A$ and $B$ are given in ascending order. There are no duplicate elements in each set.
Print elements in the difference in ascending order. Print an element in a line.
