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.

could you please help me answer this in python , the part in bold explains what they mean by ruler here

A sparse ruler of reach N is complete if it is possible to measure all distances between 1 and N by taking
the differences between two marks. For instance [0,1,3] is complete because the pairs (0, 1), (1,3), and
(0, 3) yield distances of 1, 2, and 3 respectively. (Note that the pair of marks do not need to be consecutive.)
On the other hand, [0,1,4] is not complete as there is no way to measure a distance of 2.
(d) Write a function ismyrulercomplete (myruler) which takes as input a list representing a sparse
ruler of reach N and returns True if it is complete and False otherwise.
· · · ·
Hint: Create a list of all differences between entries in the ruler. The loop through the values 1, . N
testing whether they are in the list of differences. (Remember, the line of code k in mylist will return
True or False.)
