I did not understand why are we passing the max level by reference.
What would happen had we not passed it by reference?
Pass by reference
Hello @prerna_gupta31 we are passign it by reference so that any change made in it should be reflected and not for that call only.
so that when both the levels becomes equal we can increment it.
