Create an application that lets you enter a list of positive and zero integers. That is, if you enter a negative number or an end of line (CTRL-Z), the application will be terminated. These numbers represent the altitudes. This application will count the number of hills while you are entering a number. A hill is made up of at least three different altitudes, in which these numbers must go up and then come down. Additionally, a plateau (flat surface) can exist on the top of and anywhere on the hill, where all the numbers are the same. I want this coding in Loop not in arry
