# 406. Queue Reconstruction by Height

#### Medium

***

You are given an array of people, `people`, which are the attributes of some people in a queue (not necessarily in order). Each `people[i] = [hi, ki]` represents the `ith` person of height `hi` with **exactly** `ki` other people in front who have a height greater than or equal to `hi`.

Reconstruct and return *the queue that is represented by the input array* `people`. The returned queue should be formatted as an array `queue`, where `queue[j] = [hj, kj]` is the attributes of the `jth` person in the queue (`queue[0]` is the person at the front of the queue).

 

**Example 1:**

```
Input: people = [[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]]
Explanation:
Person 0 has height 5 with no other people taller or the same height in front.
Person 1 has height 7 with no other people taller or the same height in front.
Person 2 has height 5 with two persons taller or the same height in front, which is person 0 and 1.
Person 3 has height 6 with one person taller or the same height in front, which is person 1.
Person 4 has height 4 with four people taller or the same height in front, which are people 0, 1, 2, and 3.
Person 5 has height 7 with one person taller or the same height in front, which is person 1.
Hence [[5,0],[7,0],[5,2],[6,1],[4,4],[7,1]] is the reconstructed queue.
```

**Example 2:**

```
Input: people = [[6,0],[5,0],[4,0],[3,2],[2,2],[1,4]]
Output: [[4,0],[5,0],[2,2],[3,2],[1,4],[6,0]]
```

 

**Constraints:**

* `1 <= people.length <= 2000`
* `0 <= hi <= 106`
* `0 <= ki < people.length`
* It is guaranteed that the queue can be reconstructed.

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