LACILAG Use the function design recipe to develop a function named big_diff. The function takes a list of integers. (Assume that the list has at least two integers). The function returns the difference between the largest and smallest elements in the list. For example, when the function's argument is [10, 3, 5, 6], the function returns 7. For this exercise, your function is not permitted to call Python's min and max functions. It is true that Python offers a very elegant and efficient solution (a version shown below) but in this exercise, we want you to practice writing loops. For now, this wonderful Python solution is not permitted in this lab, but free feel to file it away for later use! def big_diff( nums): return max(nums) - min(nums)
