easy - accepted / - tried

Given 2 sorted array of integers, find the elements that exist in both arrays.

```
intersect(
[1,2,2,3,4,4],
[2,2,4,5,5,6,2000]
)
// [2,2,4]
```

- The arrays might have duplicate numbers.
- The order of returning result doesn't matter.
- What is the time & space cost of your approach? Could you improve it?
