Problem

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 fom Bob's challenge is the triplet b = (b[0], b[1], b[2]).

The task is to find 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.

Example

a = [1, 2, 3]
b = [3, 2, 1]
  • For elements 0, Bob is awarded a point because a[0].
  • For the equal elements a[1] and b[1], no points are earned.
  • Finally, for elements 2, a[2] > b[2] so Alice receives a point.

The return array is [1, 1] with Alice's score first and Bob's second.

Function Description

Complete the function compareTriplets in the editor below.

compareTriplets has the following parameter(s):

  • int a[3]: Alice's challenge rating.
  • int b[3]: Bob's challenge rating.

Return

  • int[2]: Alice's score is in the first position, and Bob's score is in the second.

Input Format

The first line contains 3 space-separated integers, a[0], a[1], and a[2], the respective values in triplet a.

The second line contains 3 space-separated integers, b[0], b[1], and b[2], the respective values in triplet b.

Constraints

  • 1 <= a[i] <= 100
  • 1 <= b[i] <= 100

Sample Input 0

5 6 7
3 6 10

Sample Output 0

1 1

Explanation 0

In this example:

  • a = (a[0], a[1], a[2]) = (5, 6, 7)
  • b = (b[0], b[1], b[2]) = (3, 6, 10)

Now, let's compare each individual score:

  • a[0] > b[0], so Alice receives 1 point.
  • a[1] = b[1], so nobody receives a point.
  • a[2] < b[2], so Bob receives 1 point.

Alice's comparison score is 1, and Bob's comparison score is 1. Thus, we return the array [1, 1].

Sample Input 1

17 28 30
99 16 8

Sample Output 1

2 1

Explanation 1

Comparing the 0^th elements, 17 < 99 so Bob receives a point.

Comparing the 1^st and 2^nd elements, 28 > 16 and 30 > 8 so Alice receives two points.

The return array is [2, 1].
