C# solution

using System; using System.Collections.Generic; using System.IO; class Solution { static void Main(String[] args) {

    int n = Convert.ToInt32(Console.ReadLine());  // Read number of test cases (but it's unused)

    // Convert string to character array

   for(int i=0; i<n;i++){
     string characters = Console.ReadLine(); 
    string result=checkChar.checkindex(characters);
    Console.WriteLine(result);
   }
      // Print result
}
class checkChar{

    public static string checkindex(string characters){
        // Read input string

string even = ""; // Initialize with empty string string odd = "";

    char[] chars = characters.ToCharArray(); 
         for (int i = 0; i < characters.Length; i++) {  // Fix loop (start from 0, use <)
        if (i % 2 == 0) {  // Check if index is even
            even += chars[i]; 
        } else {
            odd += chars[i];
        }
    }
    return even + " "+ odd;

    }
}

}

n = str(input("What is your name")) a = "" b = "" for x in range(len(n)): if x%2 == 0: a+=n[x] elif x%2 != 0: b+=n[x] print(a+""+b)

This is my code. it gives right output in pycharm but why cant i pass the test cases?/ anyoone please help

**SUCCESSFULLY COMPLETED THIS PROGRAM ** PLEASE LET ME KNOW, TO OPTIMIZE THIS!!

// import java.io.; import java.util.;

public class Solution {

public static void Testcase(String s)
{
    char[] ch = s.toCharArray();
    char[] ab = new char[5000];
     char[] bc = new char[5000];

    int g=0;
    int h=0;

    for(int i=0;i<s.length();i++)
    {
        if(i%2==0)
        {
            ab[g++]=ch[i];
        }
        else
        {
            bc[h++]=ch[i];
        }
    }
    System.out.println(new String(ab,0,g)+" "+new String(bc,0,h));

}

public static void main(String[] args) {
    /* Enter your code here. Read input from STDIN. Print output to STDOUT. Your class should be named Solution. */
    Scanner sc = new Scanner(System.in);

    int a = sc.nextInt();
    String s;

    for(int j=1;j<=a;j++)
    {
        s = sc.next();
        Testcase(s);
    }

}

}

test_cases = int(input()) strings = []

for _ in range(test_cases): strings.append(input())

for item in strings: even_index = item[0:len(item):2] odd_index = item[1:len(item):2] print(even_index,odd_index)

here I Got this output...

Scanner sc=new Scanner(System.in); int n=sc.nextInt(); sc.nextLine(); for (int i = 0; i

     char[] a= str1.toCharArray();

      //printing the even of strings
   // System.out.println(c);
    for(int c=0;c<a.length;c++){ 
        if(c%2==0) {
           System.out.print(""+a[c]);
           }}
        System.out.print(" ");
        for(int c=0;c<a.length;c++){
        if(c%2!=0){
        System.out.print(a[c]);}
        }
        System.out.println();
    }
