Recursion is a powerful tool. In Python, write a recursive function that compute the minimum element in an array. Rather than get a series of elements from the user, build a random number generator and have the user designate the number of elements to be put into the array. Once that is selected, use a for loop to generate the number of elements to be stored into the array and use a recursive function to go through the array and locate the smallest element. Ensure you put forth error messages for any input that is not an integer.
