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();
    }
