# HackerRank Compare The Triplets solution

Hello Programmers, In this post, you will learn how to solve HackerRank Compare The Triplets solution. This problem is a part of the HackerRank Algorithms Series.

One more thing to add, don’t straight away look for the solutions, first try to solve the problems by yourself. If you find any difficulty after trying several times, then look for the solutions. We are going to solve the HackerRank Algorithms problems using C, CPP, JAVA, PYTHON, JavaScript & SCALA Programming Languages.

## HackerRank Compare The Triplets

### 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 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.

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 2a[2] > b[2] so Alice receives a point.

The return array is [1, 1] with Alices 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 0th elements, 17 < 99 so Bob receives a point.
Comparing the 1st and 2nd elements, 28 > 16 and 30 > 8 so Alice receives two points.
The return array is [2, 1].

### FAQ:

#### 1. How do you solve the first question in HackerRank?

If you want to solve the first question of Hackerrank then you have to decide which programing language you want to practice i.e C programming, Cpp Programing, or Java programming then you have to start with the first program HELLO WORLD.

#### 2. How do I find my HackerRank ID?

You will receive an email from HackerRank to confirm your access to the ID. Once you have confirmed your email, the entry will show up as verified on the settings page. You will also have an option to “Make primary”. Click on that option. Read more

#### 3. Does HackerRank detect cheating?

#### 4. Does HackerRank use camera?

No for coding practice Hackerrank does not use camera but for companies’ interviews code submission time Hackerrank uses the camera.

#### 5. Should I put HackerRank certificate on resume?

These certificates are useless, and you should not put them on your resume. The experience you gained from getting them is not useless. Use it to build a portfolio, and link to it on your resume.

#### 6. Can I retake HackerRank test?

The company which sent you the HackerRank Test invite owns your Test submissions and results. It’s their discretion to permit a reattempt for a particular Test. If you wish to retake the test, we recommend that you contact the concerned recruiter who invited you to the Test and request a re-invite.

#### 7. What is HackerRank?

HackerRank is a tech company that focuses on competitive programming challenges for both consumers and businesses. Developers compete by writing programs according to provided specifications. Wikipedi
