plz help me to solve ths 2 question-
Q1:- Write a program which takes a string as input and give the position of all matching brackets as output.
E.g. input is “{{}{{}{}}{}}”

And output should be:

     Bracket on position 2 matches with brackets on position 3
     Bracket on position 5 matches with brackets on position 6
      Bracket on position 7 matches with brackets on position 8
      Bracket on position 10 matches with brackets on position 11

Q2:- A string can accept only a-z (all alphabets without repetition).Now a string is say, “REPEATABLE”. Now whenever it contains a repeated alphabet(E ,A in this case)then the second repeated letter should be deleted as well as the letter after it also should be deleted from the string. So the output will be “REPTABL”. Write a programme to give the output.

I need the code in c#.Thanks

You wont find many people on here willing to do your homework for you.

To quote a fellow member on these forums:

"You might be lucky and find someone who's in the Christmas spirit, but my own approach on this list is that I'm happy to help people who have a specific question or a specific difficulty, but I don't provide a free programming service."

You might try writing your problem out in psuedo code in whatever language you feel comfortable with. Sort of like:

Look at each of the characters in the string {
  If the character is an Open Bracket do ...

  Else do ...

}

From there you need to convert your psuedo code to C# code. Which is a big topic if you know nothing about C#. If you have specific questions about how to accomplish a task, ask and you may get an answer.

Happy Holidays

What you don't know can hurt you!

Regular expressions with C# should help you here if you want to do it yourself. Sample can be found here http://www.c-sharpcorner.com/UploadF...RegExpPSD.aspx and regular expressions can be read here http://www.regular-expressions.info/

Good luck.
