#3

There are few mistakes in your code,

  1. since both left and right parenthesis would make up the string so the 2*n should be passed in generateParenthesis()
  2. condition when the no of right parenthesis become more than left ones has to be set
  3. call in addition of ‘(’ braces first for the recursion to work properly.
  4. limit variable has to be initially n since max left braces can be n
    try to work out on these suggestions.
#4

  1. in the qn, we have to generate all the possible pairs of n balanced parentheses.
    so i have passed the total length as 2n.

  2. close brackt can’t be greater than the open bracket
    becoz ‘)’ is appending only when it is less than ‘(’

  3. recursion r working fine
    firstly always open bracket will make call then close bracket will make call becoz of the condition open<close

  4. as we have to generate using n pairs
    so no of left bracket == n

hope this will help u
