Its dynamic input so it may be different more than one nest bracket
eg:
add(add(15,add(4,add(5,4))),5)

or
add(add(15,5),5) how to do that??please help me give some tips !!

not only add will string it may verie length() . so depend upon on the add or length function only we decide its no or size

eg:
add(15,length(4,5)) output should be no(15)+size(4,5)
before split i need to find wich function it is? thats the pblm i am facing

Hi Dravidnsr,

It works for your string, but I need to check for other scenarios... it's still a work in progress... needs to be optimized and refactored... but since I have a plane to catch I will write it down here for you... meanwhile I will have fun in the plane finishing it... (it's C# but I think it's easy to change to java)...

         
  string s = "add(add(15,add(4,5)),5)";

            string[] left = s.Split('(');
            //string[] arguments = s.Split(',');
            //string[] right = s.Split(')');

            int xL = left.Count<string>();            //    add                   add         15,add       4,5)),5)
            //int xA = arguments.Count<string>();     //    add(add(15            add(4       5))          5)
            //int xR = right.Count<string>();         //    add(add(15,add(4,5                ,5
