The attached C# program (Recursion_Demo.cs) demonstrates the concept of recursion. The program inputs the value of n from the user and then the recursive RDemo method prints the following sequence: n (n-1) (n-2)...1123...n Execute the program and check it out for yourself. You will write a MIPS program which MUST use a non-leaf procedure to implement this recursive method. Iterative implementation of the program will NOT be accepted. Your program will define a non-leaf procedure RDemo which will be called recursively for n>=1. RDemo will return when n

PYTHON! Can someone explain this recursion problem? In my mind the ouput would be 19 because: 1st step: R(5) = -1 because (5-1)-5 then returns to top with -1 and since that is less than zero it returns 20 but subtracts the -1 it returned   def R(n):    if n<=0:        return 20    return R(n-1) - n print(R(5))

Attached is a programming question and its Java solution. My question regarding the recursion part:      1. "arr.add(j)" but then "arr.remove(arr.size() - 1)" follows soon after, and I think nothing should be printed. How does the program still print out permutations? Is it because the recursive method call only recurse all instructions from the start of the recursion method to that line? Otherwise, say the input is "5", how does "5=1+1+1+1+1" get printed?      2. Does the recursion stop when "j<=n" evaluates false because of "for(int j = i; j <= n; j++)"? Otherwise, which line of code tells the recursion to stop?

In c++, Thanks!!! Write the simplest program that will demonstrate iteration vs recursion using the following guidelines -  Write two primary helper functions - one iterative (IsArrayPrimeIter) and one recursive (IsArrayPrimeRecur) - each of which Take an array and its size as input params and return a bool such that 'true' ==> array and all elements are prime, 'false' ==> at least one element in array is not prime, so array is not prime.  Print out a message "Entering <function_name>" as the first statement of each function. Perform the code to test whether every element of the array is a Prime number. Print out a message "Leaving <function_name>" as the last statement before returning from the function. Remember - there will be nested loops for the iterative function and there can be no loops at all in the recursive function. You will need to define one other helper function (IsPrimeRecur) for the recursion which should also not contain any loops to make it a…
