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 are the total points a person earned.

Given a and b, determine their respective comparison points.

Example:

Input:  a[3]={17,28,30},b[3]={99,16,8}
Output: 2 1

Approach

C++

#include <bits/stdc++.h>
using namespace std;

int main()
{
    int a[3] = {17, 28, 30}, b[3] = {99, 16, 8};
    int alice_point = 0, bob_point = 0;
    for (int i = 0; i < 3; i++)
    {
        if (a[i] > b[i])
        {
            alice_point++;
        }
        if (b[i] > a[i])
        {
            bob_point++;
        }
    }
    cout << alice_point << " " << bob_point << "\n";
    return 0;
}
