Use recursion to ask a user for a number N, then calculate the following items: N! (N
Question:
Use recursion to ask a user for a number "N", then calculate the following items:
N! (N factorial) - the product of all the numbers from 1..N.
The Nth Fibonacci number (1, 1, 2, 3, 5, 8, ... look it up in Wikipedia).
The sum of all numbers between 1 and N.
Create a custom program, recursion.java, that prompts the user to enter a number. Then, using recursion, find the summation, factorial, and the Nth Fibonacci for the number given.
NOTE: make sure your program does not fail if an invalid response is given.
Sample Output:
Enter a positive integer: 5
The product of the numbers from 1 to 5 (5!) is: 120
The sum of the numbers from 1 to 5 is: 15
The 5th Fibonacci number is: 5
