Hackerrank - Compare the Triplets solution

Hackerrank - Compare the Triplets solution

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.

We define the rating for Alice's challenge to be the triplet , and the rating for Bob's challenge to be the triplet .

Your task is to find their comparison points by comparing  with ,  with , and  with .

  • 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  and , determine their respective comparison points.

For example,  and . For elements , Bob is awarded a point because . For the equal elements  and , no points are earned. Finally, for elements ,  so Alice receives a point. Your return array would be  with Alice's score first and Bob's second.

Function Description

Complete the function compareTriplets in the editor below. It must return an array of two integers, the first being Alice's score and the second being Bob's.

compareTriplets has the following parameter(s):

  • a: an array of integers representing Alice's challenge rating
  • b: an array of integers representing Bob's challenge rating

Input Format

The first line contains  space-separated integers, , , and , describing the respective values in triplet .
The second line contains  space-separated integers, , , and , describing the respective values in triplet .

Constraints

Output Format

Return an array of two integers denoting the respective comparison points earned by Alice and Bob.

Sample Input 05 6 73 6 10

Sample Output 01 1

Explanation 0

In this example:

Now, let's compare each individual score:

  • , so Alice receives ¬†point.
  • , so nobody receives a point.
  • , so Bob receives ¬†point.

Alice's comparison score is , and Bob's comparison score is . Thus, we return the array .

Sample Input 117 28 3099 16 8

Sample Output 12 1

Explanation 1

Comparing the  elements,  so Bob receives a point.
Comparing the  and  elements,  and  so Alice receives two points.
The return array is .
