# PROBLEM:

Given the decisions of four referees as to whether a ball was in or out, decide whether the ball was indeed in or not. It is considered to be in if and only if all 4 referees say that it is in.

# EXPLANATION

Simply check if all 4 numbers given in the input are 0 or not. If they are, print “In”, otherwise print “Out”.

This check can be done in several ways, for example:

• Apply an if condition to each input integer
• Or, find the sum of all 4 numbers and check if this is zero

# TIME COMPLEXITY

\mathcal{O}(1) per test case.

# CODE:

Editorialist's code (Python)
for _ in range(int(input())):
print('In' if sum(map(int, input().split())) == 0 else 'Out')
