Here is a class called PriorityQueue:
class PriorityQueue:
def __init__(self):
self.items = []
def isEmpty(self):
return self.items == []
def insert(self, item):
self.items.append(item)
def remove(self):
maxi = 0
for i in range(1, len(self.items)):
if self.items[i] > self.items[maxi]:
maxi = i
item = self.items[maxi]
return item
My question concerns the remove function. The
function returns the maximum value. However, I'm
curious about
self.items[maxi:maxi+1] = []. I understand that the
programmer wants to remove self.items[maxi]. Why
would he or she want to remove that value and the one
next to it (maxi+1)? Or am I misunderstanding
self.items[maxi:maxi+1] = [] ?
As an aside, I can't figure out how to respond to
topics on this list.
