In this exercise, you'll write a function named square to compute the square of a number. Squaring a number means multiplying it by itself. Your function should take one parameter and return the squared value. Your function should return the square of the number, not print it$.$ Instead, you'll need to store the value returned by the function call into a variable. For example, the following code should put the value $25$ in x$.$ x square$(5)$ Call your square function at least two times with different numbers, and print the results each time to check your function's output. Note: Be sure to include comments for all functions that you use or
