Dear Expert,

I'm trying to fix this code :

function println(str) {

}

function set_indent(i) {
   var indent = i;
}

function mystr(str) {
   pre = "";
   for (var i=0; i<indent;i++) {
       pre+=" ";
   }
   return pre + str;
}

function printtable(size) {
   set_indent(0);
   println("This is a pyramid");
   for (var i=0; i<size; i++) {
       set_indent(size*2-i);
       s="";
       for (var j=0; j<i*2+1;j++) {
           s += "*";
       }
       println(mystr(s));
   }
}

indent=0;
printtable(5);

to make the output look like this:


This is a pyramid

        *

       ***

      *****

     *******

    *********

But it's doesn't work... Can you help to find the bug in the code?
and help me to finishing the function println.


Thanks
