Answer 1

I believe that the number of possible permutations of n objects is n! (n factorial)

Answer 2

Jan Markus you use predefined method right ?

Answer 3

Jan Markus yeah true but most of time almost 90% we don't know is there any method available for certain task ...

Answer 4

Jan Markus Yes indeed and I really like your approach but I mentioned that I "believe" that to find the total number of permutations of n one has to calculate n! (factorial)

Answer 5

Uni alright first I didn't mention arrangement so it could possibly repeat and

how it's n! ? permutations isn't equal to n!

Answer 6

Jan Markus I have started java few days ago and it's even more hard to implement a predefined method

I have learned basics of C++ it was really easy and straight forward..

Answer 7

isn't 2^n formula ?
