Recursive case idea

#1

please give me the idea of recursive case

#2

You can read it here. Pictorial representation will help you understand better.

#3

sorry but i don’t get the code as it is in java thats why i can’t get explanation of pictorial representation.
it is better if you can give the approach of this whole question means how to come up with idea.

#4

sir please tell me the timings of doubt assistant as this is wasting a lot of time or in other case i loose interest in
any question which i have asked earlier as we move further in the course section

#5

I mostly solve doubts late night , I don’t know exact timing of other TA’s. You can post your doubt late at night. Meanwhile you can solve more problems.
You can see my implementation in C++.

#6

sir but i need approach to this question
i can’t get the code

  • open = open parenthesis
    • close = close parenthesis
    • position = 2*n (length of combination of valid parenthesis
    • n = pair of parenthesis
    • Algorithm:
    • 1.Check if position == 2*n – Yes, print the str
    • 2.check if open is less than n
    •  If true, add a open parenthesis into str and  call the function recursively by 

    •  incrementing open by 1 and position by 1
    • 3.check if close < open
    •  If true , add a close parenthesis and call the function recursively by 

    •  incrementing close by 1 and position by 1*/
