Hi Madan,

Based on your latest update, your question should be like

Count possible combinations of curly braces pairs. Correct me if this is wrong.

Hi Madan,

{{{}}}, score of 1 + 2 + 3 = 6.

Can you expalin, How it is 6?

My understanding is
{{{}}} + {{{}}} + {{{}}} + {{{}}} + {{{}}}

{{{}}} + {{{}}} + {{{}}} + {{{}}} = 9

string s = "your string value";
Console.WriteLine( s.Select((c, i) => s.Substring(i)).Count(sub => sub.StartsWith("},"))

Sample Code gives you output 6 for this input. and I hope this is what you expected.

1.{
2. {
3.    {},
4.    {},
5.    {
6.        {}
       }
     }
   }

Hi,

You can write somethihg like this.
class Program
    {
        static void Main(string[] args)
        {
            var mystring = "{{}}}, score of 1 + 2 + 3 = 6.";

            var start = mystring.Count(x => x == '{');
            var end = mystring.Count(x => x == '}');
            int count = 0;
            // if all braces have proper closing
            if (start == end)
            {
                count = start;
            }
            else
            {
                // else we will count for only those braces with having proper start & end
                if (start > end)
                {
                    count = end;
                }
                else
                {
                    count = start;
                }
            }
            Console.WriteLine("Count : " + count);
            Console.Read();
        }
    }
Hope this will help you.
