c#

Console.Write((i+Convert.ToInt32(Console.ReadLine()))+"\n"+(d+Convert.ToDouble(Console.ReadLine())).ToString("F1")+"\n"+s+Console.ReadLine());

nextLine read leftovers also so after gving input of double we press enter nextLine reads it and returns empty so we need to add 1 more nextLine so that it can read the line we typed after pressing enter ( our input string ).

so we write it like: scan.nextLine(); // to clear buffer String str = scan.nextLine();

//in c++

/*
    cout<<4+integer_num<<'\n';
    cout<<fixed<<setprecision(1)<<4.0+double_num<<'\n';
    cout<<"HackerRank "+String<<'\n';
*/

//in c
