How do I write a method that calculates the sum of the integers between 1 and n? I thought of using n + sum (n-1), but I need to use the recursive definition that the sum of 1 to n is the sum of 1 to n/2 plus the sum of (n/2+1) to n. Assume that n is a positive integer.
4. Find f(2), f(3), f(4), and f(5) if f is defined recursively by f(0) = f(1) = 1 and for n = 1,2, ...
a) f(n + 1) = f(n) - f(n - 1).
b) f(n + 1) = f(n)f(n - I).
c) f(n + 1) = f(n)^2 + f(n - 1)^3.
d) f(n + 1) = f(n)/f(n - 1).
Need help finishing a program. It's the hanoi tower recursion program. In addition to what I have, I also need a function that:
1. tells how long my computer takes to move the disk (in seconds)
2. if someone can move 1 disk per second, how long would it take them to move 100 disc?
Both functions should be recursive and I'm
Determine whether each of these proposed definitions is a valid recursive definition of a function f from the set of non negative integers to the set of integers. If f is well
defined, find a formula for f(n) when n is a non negative integer and prove that your formula is valid.
a) f(0) = 1,f(n) = - f(n - 1) for n >= 1
Please provide a little guidance on how to solve the following problem using recursion. I can understand solving it using iteration .. but not recursion.
Design a game called Jump it.
It consists of a board of n integers rows. All containing positive integers except the first one always containing 0.

I need a recursive function that accepts an integer and returns its reverse.
int reverse( int n );
n = reverse (123) ; // this returns 321
I can do this easily without recursion but I have to use recursion.
(a) Use this reursion formula, c_j+1 = (2(j+l+1-n)*c_j)/((j+1)(j+2l+2)), to confirm that when l=n-1 the radial wave function takes the form:
R_n,n-1 = (N_n)*r^(n-1)*e^(-r/(na))
(b) Calculate and for states psi_n,n-1,m.
A. What is direct recursion?
b. What is tail recursion?
c. Suppose hat intArray is an array of integers, and length specifies the number of elements in intArray. Also suppose that low and high are two integers such that 0 <= low < length. 0 <= high < length, and low < high. That is, low and high are two indices in intArray
