Solve the questions on recursive function; please refer to the screenshot; 1)a)b)Consider the following recursive function. You can assume that it will be invoked withnon-negative integers.int mystery (int n,{}= m)if (n ==return n;int m)else if (n == 0)return m;else if (m == 0)return n;elsereturn mystery(m, n % m);Trace the execution of the three function calls mystery(363, 55), mystery(126, 49), andmystery(81, 37).For each of these three cases, how many calls do each of them make until they return theanswer? What are the values of the parameters in each of the calls? Which base case dothey reach?What does the mystery function actually do? Can you connect it to a known algorithmfor solving this problem?

a) In summary:For mystery(363, 55), it takes 5 calls to reach the base case.For mystery(126, 49), it…

Answered: 1) a) b) Consider the following…

MULTIPLE FUNCTIONS AND RECURSIVE FUNCTIONS Use #include<stdio.h> Implement the picture shown below.
Question 2: Implementing a Recursive Function .Write recursive function, recursionprob(n), which takes a positive number as its argument and returns the output as shown below. The solution should clearly write the steps as shown in an example in slide number 59 and slide number 60 in lecture slides. After writing the steps, trace the function for “recursiveprob(5)” as shown in an example slide number 61. Function Output: >> recursionprob(1) 1 >> recursionprob(2) 1 4 >> recursionprob(3) 1 4 9 >>recrusionprob(4) 1 4 9 16
8. A country has coins of denomination 3, 5 and 10 respectively. Write a recursive function canchange() which returns -1 if it is not possible to pay a value of k using these coins. Otherwise, it returns the minimum number of coins needed to make the payment. For example, canchange(7) will return -1. On the other hand, canchange(14) will return 4 because 14 can be paid as 3+3+3+5 and there is no other way to pay with fewer coins
MULTIPLE FUNCTIONS AND RECURSIVE FUNCTIONS .
code is to be written in C A palindrome is a word that reads the same forward and backwards. For example, “mom”, “dad”, “anna”, “racecar”, “rotor”, “radar”, etc. Write a recursive function that determines if a word and/or phrase is a palindrome. Develop 5 test char arrays in main() (no user input is required) that are passed to your recursive palindrome function to test it. Your function should not return any values but should output to the screen the word passed and whether or not it is a palindrome. You may use string.h but NO STRING REVERSE functions…you must write your own RECURSIVE string reverse function. Submit this assignment to me by sending your source code in the body of an email.
3. Write a recursive function that ассepts 8x8 array of an characters that represents a maze. Each position can contain either an X or a blank. Starting at position (0,1), list any path through the maze to get to the location (7,7). Only horizontal and vertical moves are allowed. If no path exists, write a message indicating there is no path. Moves can be made only to the locations that contain a blank. If an X is encountered, that path is blocked and another must be chosen.

09. Question Write a recursive function printRev ( int a[ ], int s, int e) that receives an integer array a [ ], a start index s, and an end index e. The function should print the array elements in reverse order. void printRev ( int a[ ], int s, int e); Trace your function given the following array and function call. Draw your steps. int a[ ] = {4, 2, 3, 5};and printRev(a, 0, 3); language c++ .

In c++ please with clear indentation thank you so much 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 Takes an array of integers and its size as input params and returns a bool such that 'true' ==> all elements of the array are prime, so the array is 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 executed 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 executed 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. For the recursive function - define one…
Q1: Write a program using function with Return Type and with Parameter to print out all Palindrome numbers between 501 and 550. Q2: A 5-digit positive integer is entered through the keyboard, write a function to calculate multiplication of digits of the 5-digit number: (1) Without using recursion (2) Using recursion Q3: To fully define a variable one needs to mention not only its 'type' but also its 'other properties'. In other words, not only do all variables have a data type, they also contain other properties. Explain the concept that will help us to describe the properties of any variable. Q4: Write a short note on Array.
