Compare the Triplets | Hackerrank C++

Compare the Triplets Alice and Bob each created one problem for HackerRank. 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 the triplet a = (a[0], a[1], a[2]) , and the rating for Bob's challenge is the triplet b = (b[0], b[1], b[2]) . The task is to find their comparison points by comparing a[0] with b[0] , a[1] with b[1] , and a[2] with b[2] . If a[i] > b[i] , then Alice is awarded 1 point. If a[i] < b[i] , then Bob is awarded 1 point. If a[i] = b[i] , then neither person receives a point. Comparison points is the total points a person earned. Given a and b , determine their respective comparison points Sample Input: 5 6 7 3 6 10 Sample Output: 1 1 CODE: #includ...
