Question

An ordinary ruler is a straight piece of wood where distances 0, 1, 2 . . . , N are marked, for some N ≥ 1. A sparse ruler (or simply a ruler ) is an ordinary ruler from which some of the numbers 1, . . . , N −1 may have been deleted. The number of marks on the ruler is its order and the value N is its reach. Here, we will represent a ruler as a Python list of strictly increasing integers starting with 0. For instance [0,1,3,7] is a ruler of order 4 and reach 7.

can you please provide the code for this question in python , the part in bold gives a background .

Write functions reach(myruler) and order(myruler) which take as input a list representing a
sparse ruler and return its reach and order, respectively.
Write a function isitaruler (mylist) which takes as input a Python list, and returns True if the list
represents a ruler (that is to say: every entry is an integer, the list starts with 0, and each subsequent
entry is strictly greater than the previous one), and False otherwise.
Hint: Set a variable called oksofar == True which you can set to False if you find a problem. First
test whether the list's initial entry equals 0. Then loop through the remaining entries testing whether they
are integers with each strictly greater than the previous.
