Solution

When we open the task we see the square with a lot of encodings.

\u0020\u0020\u0020\u0020\u0020\u0020
\u0070\u0075\u0062\u006c\u0069\u0063
\u0063\u006c\u0061\u0073\u0073\u0020
\u0052\u0075\u006e\u004d\u0065\u007b
\u0070\u0075\u0062\u006c\u0069\u0063
\u0073\u0074\u0061\u0074\u0069\u0063
\u0076\u006f\u0069\u0064\u0020\u0020
\u006d\u0061\u0069\u006e\u0028\u0020
\u0053\u0074\u0072\u0069\u006e\u0067
\u005b\u005d\u0020\u0061\u0072\u0067
\u0029\u0020\u007b\u0020\u0020\u0020
\u0053\u0079\u0073\u0074\u0065\u006d
\u002e\u006f\u0075\u0074\u002e\u0020
\u0070\u0072\u0069\u006e\u0074\u0028
\u0022\u0022\u0022\u0020\u0020\u0020
\u002f\u0079\u006f\u0075\u002d\u0020
\u0064\u0069\u0064\u002d\u0020\u0020
\u0069\u0074\u0020\u0020\u0020\u0020
\u0022\u0022\u0022\u0020\u0020\u0020
\u0029\u003b\u007d\u007d\u0020\u0020

All these encodings are starting wih /u symbol.

So we grab any unicode decoder and decode this text. We recieve following code (formatted):

public class RunMe {
  public static void main( String [] arg ){
    System.out.print( "/you-did-it" );
  }
}

If we run this code we will get /you-did-it in our console.

So our result url will be:
http://18.198.170.188:80/you-did-it

If we go to this url we will see congratulations page
whith the link to the Level 5 ( task / solution )
