Sample Code gives you output 6 for this input. and I hope this is what you expected. 1.{ 2. { 3. {}, 4. {}, 5. { 6. {} } } }

Hi Madan, {{{}}}, score of 1 + 2 + 3 = 6. Can you expalin, How it is 6? My understanding is {{ {} }} + { { {} } } + {{ { } } } + { { { } }} + { {{}} } {{ { }} } + { {{ } }} + { {{} } } + { { {}} } = 9

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.
