406. Queue Reconstruction by Height
https://leetcode.com/problems/queue-reconstruction-by-height/
这么理解先插高的,这样当我们使用insert(pos,number) 我们能保证pos之前的都是比number大的数

class Solution:
def reconstructQueue(self, people: List[List[int]]) -> List[List[int]]:
people.sort(key=lambda x: (-x[0],x[1]))
res = []
for p in people:
res.insert(p[1],p)
return res
