Suppose you have a random list of people standing in a queue. Each person is described by a pair of integers
(h, k), where
h is the height of the person and
k is the number of people in front of this person who have a height greater than or equal to
h. Write an algorithm to reconstruct the queue.
The number of people is less than 1,100.
