Suppose you have a random list of people standing in a queue. Each person is described by a pair of integers(h, k), wherehis the height of the person andkis the number of people in front of this person who have a height greater than or equal toh. Write an algorithm to reconstruct the queue.
Note:
The number of people is less than 1,100.
Example
Input: [[7,0], [4,4], [7,1], [5,0], [6,1], [5,2]]
Output: [[5,0], [7,0], [5,2], [6,1], [4,4], [7,1]]
h 为身高, k为排在他前面的身高大于等于他身高的人数。
step1: 身高降序排列, 如果身高一致,很显然k要升序排列。
list to array 时候要在参数里new 一个int的数组! 这个输入参数的格式作为模板传进去, 等返回来时,已经装满了数据。 想想满满的幸福感。
