解法一:
class MyCalendarTwo:
def __init__(self):
self.lst1 = []
self.lst2 = []
def book(self, start: int, end: int) -> bool:
for l, r in self.lst2:
if max(start, l) < min(end, r):
return False
for l, r in self.lst1:
t1, t2 = max(start, l), min(end, r)
if t1 < t2:
self.lst2.append([t1, t2])
self.lst1.append([start, end])
return True
