Question
Question 4: (Find the minimum value in an array) Write a
recursive function “recursiveMinimum” that takes an integer array and the array size as
arguments and returns the smallest element of the array. The function should stop
processing and return when it receives an array of one element.

- Part 2: Unroll Write a function called unroll, which takes in a square array of arrays (i.e. a grid with n rows and n columns). An input could look like this: const square = [ [1, 2, 3, 4], [5, 6, 7, 8], ]; [9, 10, 11, 12], [13, 14, 15, 16] unroll should take in such a square array and return a single array containing the values in the square. You should obtain the values by traversing the square in a spiral: from the top- left corner, move all the way to the right, then all the way down, then all the way to the left, then all the way up, and repeat. For the above example, unroll should return [1, 2, 3, 4, 8, 12, 16, 15, 14, 13, 9, 5, 6, 7, 11, 10].arrow_forwardO Design an algorithm to find the maximum element in a list of n unique numbers. Give a trace for get MAX(A,n), where A={1,5,2,9,4,3} and n=6. Design a recurrence relation for the algorithm and find its time complexity. Give a proof of correctness.arrow_forward1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 1.arrow_forward
- 19-8) isMember Function Write a recursive Boolean function named isMember. The function should accept three arguments: an int array, an int index number holding the size of the array and an int value to be searched for. The function should return true if the value is found in the array, or false if the value is not found in the array. Demonstrate the function in a driver program. --ORIGINAL QUESTION (Had no index variable and no type on the array)- 19-6) Recursive Power Function Write a function that uses recursion to raise a number to a power. The function should accept two arguments: the number to be raised and the exponent. Assume that the exponent is a nonnegative integer. Demonstrate the function in a program.
