These methods work, but see my comments on the time complexity. Let me know if you have questions or if I can clarify a bit.
Well done!

Slice is going to shift subsequent elements to the left one index. Thus it as a time complexity of O(n). Inside this loop your method as time complexity of O(n2)

Since you have those two nested loops you actually have a time complexity of O(n2)

Since you never change low, you may not need it. This made me think of binary search and it confused me for a bit.
