Run my function on {(1,4),(0,6),(3,5),(2,9),(7,8)}. Is the output what you expect?

Find the problem and fix it, writing a correct version of the function. Again, use the same function name, i.e., count_crossings_and_nestings. Demonstrate that the new version works by testing it on the example provided. Now write a well-documented version of your function count_crossings_and_nestings. Add a document string and plenty of comments.

def count_crossings_and_nestings(arcs):
crossings
= 0
nestings = 0
num_arcs = len (arcs)
for i in range(num_arcs):
for j in range(i+1, num_arcs):
arc1_start, arc1_end = arcs [i]
arc2_start, arc2_end = arcs [j]
if arc1_start < arc2_start < arc1_end < arc2_end:
crossings += 1
elif arc2_start < arc1_start < arc2_end < arc1_end:
crossings += 1
elif arc1_start < arc2_start < arc2_end < arc1_end:
nestings += 1
elif arc2_start < arc1_start < arc1_end < arc2_end:

return crossings, nestings
arcs = [(0, 1), (0, 2), (1, 2)]
crossings, nestings =
count_crossings_and_nestings(arcs)
print (f"Number of crossings: {crossings}")
print (f"Number of nestings: {nestings}")
