题目描述
Find the difference of two sets $A = \\{a_0, a_1, ..., a_{n-1}\\}$ and $B = \\{b_0, b_1, ..., b_{m-1}\\}$, $A - B$.
Constraints
- $1 \leq n, m \leq 200,000$
- $0 \leq a_0 < a_1 < ... < a_{n-1} \leq 10^9$
- $0 \leq b_0 < b_1 < ... < b_{m-1} \leq 10^9$
Input
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.
Output
Print elements in the difference in ascending order. Print an element in a line.
