Thank you for correcting my code. in future i’ll make sure to add comment
i had a doubt that in the code i previously wrote i tried to apply a similar logic but it didn’t work . could you please tell me the mistakes i made in the previous code
if(ob>n) //when opening brackets are more than total number of pairs
return;
if(cb>ob) //When opening brackets are less than the closing brackets:
return;
if (ob==n &&cb==n) // when all opening and closing brackets are inserted
cout<<ans<<"\n";

 generate_bracket(ans+'(',ob++,cb,n);
generate_bracket(ans+')',ob,cb++,n);

Hello @Anushka_Jha,

  1. The only mistake i can see is the missing checks before the following statements:
    generate_bracket(ans+’(’,ob++,cb,n);
    generate_bracket(ans+’)’,ob,cb++,n);

    The checks should be the same as we have in my code.

  2. The base cases you have specified would work.
    But, you can reduce them to a single base case by:
    if (ob==n &&cb==n){ // when all opening and closing brackets are inserted
    cout<<ans<<"\n";
    //Add a return statement here:
    return;
    }

Hope, this would help.
