There are (N-1)! ways to eat chocolates from left to right.

• The first chocolate can be chosen in N ways, the second in (N-1) ways, and so on.

• However, since the order of chocolates eaten matters, we need to divide by the number of ways to order N chocolates, which is N!.

• Therefore, the total number of ways to eat chocolates is (N-1)!

• For example, if N=4, there are 3! = 6 ways to eat the chocolates.
