PROBLEM:
There is a contest containing 2 problems A and B.
2 strong participants P and Q participated in the contest and solved both the problems.
P made AC submissions on problems A and B at time instants P_A and P_B respectively while Q made AC submissions on problems A and B at time instants Q_A and Q_B.
It is given that the time penalty is the minimum time instant at which a participant has solved both the problems. Also the participant with the lower time penalty will have a better rank.
Determine which participant got the better rank or if there is a TIE
.
EXPLANATION:
Let X represent the time when P has solved both the problems and Y represent the time when Q has solved both the problems.
X=max(P_A,P_B)
Y=max(Q_A,Q_B)
Since the time penalty is the minimum time instant at which a participant has solved both the problems and the participant with the lower time penalty will have a better rank. Hence if X<Y the participant with a better rank is P otherwise if Y<X the participant with a better rank is Q else it is a TIE
.
TIME COMPLEXITY:
O(1) for each test case.
