use octave or MATLAB as programs to code. do not usedisp or num2str. also, do not use break or continuestatements.

3. In this problem we will investigate using recursion to determine whether or not a user- entered vector is sorted (either nondecreasing or nonincreasing). Given a length-1 vector, it clearly is sorted and we will say it’s nondecreasing. Given a length-2 vector, we can easily determine if it’s sorted by comparing the two elements. Given a vector of length > 2, we can break the problem down by noting that if we knew the status and smallest and largest elements of the subvector of elements 2 through the end, we could use them and the value of the first element to determine the status of the given vector. Write a program that calls the function get vector which should • call the function get positive integer (passing in an appropriate string) once to obtain a value for the length of the vector • use a loop to prompt the user to enter the vector one element at a time • return the entered vector and its length. The function get.positive integer should • take in a string input variable to use in the prompt • keep prompting the user and giving error messages (tising %a) until a positive integer is entered • return the resulting value. The main programi should then call the function check if sorted wbich should • take in a vector of numbers and its length • print an “entering status message giving the input mirable values • call itself recursively to determine if the vector is moderning Bo s ing or not sorted (if it is both nondecreasing and nonincreasing call it hon i ng • print loving an age giving the rol variable value • return • print a “leaving” status message giving the output variable values return Da status integer that is equal to 1 if the vector is nondecreasing, -1 if it is nonincreasing, and 0 if it is not sorted the smallest integer present in the input vector if it is sorted or otherwise set equal to -99999 the largest integer present in the input vector if it is sorted or otherwise set equal to 99999 The main program should then print a message based upon the status.
