~ no response on stdout ~ C# Error while submitting code in HackerRank

Question

I am practicing C# code on HackerRank online website, when I want to submit my code then it gives an error:

Below is my code:

for(int i=0;i<input.Count-1;i++){
        string evenData="",oddData="";
        string data=input[i];
        for(int j=0;j<data.Length-1;j++){
            
            if(i%2==0){
                evenData += data[j].ToString();
            }else{
                oddData +=data[j].ToString();
            }
        }
        Console.WriteLine(evenData + " " +oddData);
    }

I have already search over the internet for this issue but everyone says just add Console.WriteLine because stdout and Console.writeLine both are just like same but it doesn't resolve my problem. Kindly provide me a better solution. Thanks

Answer 1

Use Console.In.ReadLine() and Console.Out.WriteLine() for stdin and stdout.

using System;
using System.Collections.Generic;
using System.IO;
class Solution {
    
    public static void Result(string s)
    {
        var sarry = s.ToCharArray();
        if(sarry.Length >1)
        {
            var evenstr = "";
            var oddstr  = "";
            
            for(int i=0 ;i<=sarry.Length-1 ; i++)
            {
                if(i%2==0)
                    oddstr=oddstr+sarry[i];
                else
                    evenstr=evenstr+sarry[i];
            }
            var result =oddstr+" "+evenstr;
            Console.Out.WriteLine(result);            
        }
    }
    
    static void Main(String[] args) {
        
        int T=int.Parse(Console.In.ReadLine());
        for (int i = 0; i < T; i++) 
        {
            var inp=Console.In.ReadLine();
            Solution.Result(inp);
        }
    }
}
