Alice and Bob each created one problem. A reviewer rates the two challenges, awarding points on a scale from 1 to 100 for three categories: problem clarity, originality, and difficulty.
The rating for Alice's challenge is defined to be the triplet A=(a0,a1,a2) , and the rating for Bob's challenge to be the triplet B=(b0,b1,b2) .
The task is to find their comparison points by comparing a0 with b0, a1 with b1, and a2 with b2.
If ai>bi, then Alice is awarded point. If ai<bi, then Bob is awarded point. If ai=bi, then neither person receives a point. Comparison points is the total points a person earned.
