I wanted to ask that at this time when the teacher is doing dry run by using the call stack then why is he multiplying the ans returned by the top most call stack with the value of a , even though there is no such instruction in the code as I have also dry run it
At the time 9:10
@jsn853 hey their is a if condition specially written in program which tells us when we need to multiply the returned value after squaring to a.
We multiply it with a after squaring when n is odd.
If this resolves your doubt mark it as resolved.
