Hi, everyone

I defined an int array in Sophia. How do I find the middle number in the array

Since Sophia is a functional language, I have been working on this problem for a long time

For example

```
[10,1,3,8,7,3,5,7,1,9,1]
```

How do I find an intermediate value in an array？

If possible, please help to write out, thank you

@hanssv.chain @hanssv2 You know what?
