Consider a rectangle ABCD, we’re given the co-ordinates of the mid points of side AD and BC (p and q respectively) along with their length L (AD = BC = L). Now given the parameters, we need to print the co-ordinates of the 4 points A, B, C and D.

Input:
The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. Each test case contains coordinates of the two mid points in 2 lines. The last line contains the integer length L.

Output:
Print the floor of the coordinates of the 4 points A,B,C and D in 4 lines.

Constraints:
1<=T<=10^5
1<=L<=10^5
1<=p,q<=L

Example:
Input:

2
1 0
1 2
2
1 1
-1 -1
2.82842712475

Output:
0, 0
0, 2
2, 2
2, 0
0, 2
-2, 0
0, -2
2, 0
