Compare the Triplets

FRom hackerrank

Alice and Bob each created one problem for HackerRank. A reviewer rates the two challenges, awarding points on a scale from  to  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 , then Alice is awarded  point.
• If , then Bob is awarded  point.
• If , 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.

Solution in C# -

class Solution {

    static List<int> compareTriplets(List<int> a, List<int> b) {

        List<int> results = new List<int>(){0,0};

       for(int i=0;i<3;i++)

        {

            if(a[i] > b[i])

            results[0]++;

            else if(a[i] == b[i])

            continue;

            else

            results[1]++;

        }

        return results;

    }

    static void Main(string[] args) {

        TextWriter textWriter = new StreamWriter(@System.Environment.GetEnvironmentVariable("OUTPUT_PATH"), true);

        List<int> a = Console.ReadLine().TrimEnd().Split(' ').ToList().Select(aTemp => Convert.ToInt32(aTemp)).ToList();

        List<int> b = Console.ReadLine().TrimEnd().Split(' ').ToList().Select(bTemp => Convert.ToInt32(bTemp)).ToList();

        List<int> result = compareTriplets(a, b);

        textWriter.WriteLine(String.Join(" ", result));

        textWriter.Flush();

        textWriter.Close();

    }
