You are given an integer array A of size $5$ and an integer b$.$ You have to find out all pairs of elements from array A whose sum is equal to $b$ and print them.

In the first line, you are given integer b$.$

In the next line, you are given $n$ integers $($the elements of array $A).$

Output each new pair in a new line.

Example

Input:

Enter the target sum$($b$)$ : $5$

Enter the elements of array A :
