 Hello everyone! Here's my solution of the question-'Three Friends' from Codeforces. Any suggestion for me is highly appreciated. Happy Coding!

question link: https://codeforces.com/problemset/problem/1272/A

#include <bits/stdc++.h>

#define long long long int

using namespace std;

int main()

{

    int q;

    cin>>q;

    int d[q];

    for(int m=0;m<q;m++){

        int a,b,c,min=1999999999;

        cin>>a>>b>>c;

        int a1[3]={a+1,a,a-1};

        int b1[3]={b+1,b,b-1};

        int c1[3]={c+1,c,c-1};

        for(int i=0;i<3;i++){

            for(int j=0;j<3;j++){

                for(int k=0;k<3;k++){

                    int s=abs(a1[i]-b1[j])+abs(b1[j]-c1[k])+abs(c1[k]-a1[i]);

                    if(min>s) {min=s;}

                }

            }

        }

        d[m]=min;

    }

    for(int i=0;i<q;i++) cout<<d[i]<<'\n';
