## 32. Find First and Last Position of Element in Sorted Array

60%

Write a function `solve` that finds the starting and ending position of a target value in a sorted array. If the target is not found, return 
[-1,-1]. Ideally, your solution should run in O(logn) time.

**Example:** `Input: [5,7,7,8,8,10], 8`  `Output: [3,4]`

Make sure you `return` your solution, don't print!

### Python3

```python
def solve(nums, target):
    pass
```
