# Compare the Triplets | Hacker rank Solutions

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 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 â‰¤ a[i] â‰¤ 100
1 â‰¤ b[i] â‰¤ 100```

Sample Input 0

5 6 7
3 6 10

Sample Output 0

1 1

Explanation :

a = (5,6,7)

b = (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].

## Solution in Python

```#!/bin/python3

import math
import os
import random
import re
import sys

# Complete the compareTriplets function below.
def compareTriplets(a, b):
pointa=0
pointb=0
ar = []
for i in range(3):
if a[i]>b[i]:
pointa+=1

if a[i]<b[i]:
pointb+=1
ar.insert(0,pointa)
ar.insert(1,pointb)
return(ar)

if __name__ == '__main__':
fptr = open(os.environ['OUTPUT_PATH'], 'w')

a = list(map(int, input().rstrip().split()))

b = list(map(int, input().rstrip().split()))

result = compareTriplets(a, b)

fptr.write(' '.join(map(str, result)))
fptr.write('\n')

fptr.close()
