You are given an array of unique numbers. The numbers represent points. The higher the number the higher the points.  
In the array [1,3,2] 3 is the highest point value so it gets 1st place. 2 is the second highest so it gets second place. 1 is the 3rd highest so it gets 3rd place. 

Your task is to return an array giving each number its rank in the array.  
input // [1,3,2] 
output // [3,1,2]

```rankings([1,2,3,4,5]) // [5,4,3,2,1]``` 
```rankings([3,4,1,2,5])//  [3,2,5,4,1]``` 
```rankings([10,20,40,50,30]) //  [5, 4, 2, 1, 3]``` 
```rankings([1, 10]) //   [2, 1]``` 
```rankings([22, 33, 18, 9, 110, 4, 1, 88, 6, 50]) //```
```[5, 4, 6, 7, 1, 9, 10, 2, 8, 3]```
