题目描述
Alex, Bob, and, Chef are standing on the coordinate plane. Chef is standing at the origin (coordinates (0, 0)) while the location of Alex and Bob are (X_{1}, Y_{1}) and (X_{2}, Y_{2}) respectively.
Amongst Alex and Bob, find out who is at a farther distance from Chef or determine if both are at the same distance from Chef.
------ Input Format ------
- The first line of input will contain a single integer T, denoting the number of test cases.
- The first and only line of each test case contains four space-separated integers X_{1}, Y_{1}, X_{2}, and Y_{2} — the coordinates of Alex and Bob.
------ Output Format ------
For each test case, output on a new line:
- ALEX, if Alex is at a farther distance from Chef.
- BOB, if Bob is at a farther distance from Chef.
- EQUAL, if both are standing at the same distance from Chef.
You may print each character in uppercase or lowercase. For example, Bob, BOB, bob, and bOB, are all considered identical.
------ Constraints ------
$1 ≤ T ≤ 2000$
$-1000 ≤ X_{1}, Y_{1}, X_{2}, Y_{2} ≤ 1000$
----- Sample Input 1 ------

8 -6 0 5
----- Sample Output 1 ------
BOB
EQUAL
ALEX
----- explanation 1 ------
Test case $1$: Alex is at a distance $1$ from Chef while Bob is at distance $5$ from Chef. Thus, Bob is at a farther distance.
Test case $2$: Alex is at a distance $5$ from Chef and Bob is also at distance $5$ from Chef. Thus, both are at the same distance.
Test case $3$: Alex is at a distance $10$ from Chef while Bob is at distance $5$ from Chef. Thus, Alex is at a farther distance.
