There is a 8x8 chessboard in which two positions are cut-off (i.e not available for placing any piece). You are given 31 dominos , and a single domino can cover exactly two squares. Given the two positions which are cut-off , find if it is possible to cover the entire board with 31 exactly dominos so that no vacant square exists.

Here is the view of chess board with rows from 1-8 and columns from A-H.

Input

The first line of input contains T , the number of test cases.

The first line of each testcase contains X and Y , where CHESS[X][Y] is cutoff.

The second line of each testcase contains A and B , where CHESS[A][B] is cutoff.

OUTPUT

For each testcase , output "YES" if possible else "NO" on a new line.

SAMPLE INPUT
2
5 e
5 d
1 a
8 h
SAMPLE OUTPUT
YES
NO
Explanation

For the first test case , the cut-off squares are CHESS[5][E] and CHESS[5][D] which are shown as red squares in the picture below.

31 dominos are placed without any extra space left , so we output "YES".
