There are exactly N people living in a certain parallel universe. The Ith of these NN people claim to be the parent of exactly Ai off these N people. However, some of these people may be lying - the person may either be telling the truth (in which case they have exactly Ai children) or lying down (in which case they can have any number of children). It is known that each person has at most one parent. Furthermore, as one would expect, a person's child is not allowed to also be their ancestor. What is the maximum possible number of truth tellers in this universe Using C++ programming language.

Question
There are exactly N people living in a certain parallel universe. The Ith of these NN
people claim to be the parent of exactly Ai off these N people.
However, some of these people may be lying - the person may either be telling the
truth (in which case they have exactly Ai
children) or lying down (in which case they can have any number of children).
It is known that each person has at most one parent. Furthermore, as one would
expect, a person's child is not allowed to also be their ancestor. What is the
maximum possible number of truth tellers in this universe Using C++ programming
language.
