RESTRICTION: You may not use the Python built-in function you are implementing within its own implementation. In the absence of additional restrictions, you may use other Python built-in functions and methods. If given a list or sequence as input, you must not change the original list or sequence.

min() Write a function min(lst) that models a limited version of the behaviour of the builtin function. In Python, the min() function is capable of signicantly more - read about it here. Input: a non-empty sequence (list) of comparable objects 1st. Output: the smallest item in 1st. reversed() Write a function reversed(seq) that models a limited version of the behaviour of the built-in function. You may not use list slicing (i.e. seq[::-1]) in this function, although it is a cool trick to know! Input: a sequence seq. Output: a new list containing all items in 1st in reverse order. Note: Remember that a sequence can be a list, a string, a tuple, or a range, so this function must work for all these types. sum() Write a function sum(lst) that models a limited version of the behaviour of the builtin function. Input: a sequence (list) of numbers 1st. Output: the sum of all numbers in 1st
