+Use `lst[offset:]` and `lst[:offset]` to get the two slices of the list and combine them before returning.
+
+Explain briefly how the snippet works.
+
+```py
+def offset(lst, offset):
+  return lst[offset:] + lst[:offset]
+```
+
+```py
+offset([1, 2, 3, 4, 5], 2) # [3, 4, 5, 1, 2]
+offset([1, 2, 3, 4, 5], -2) # [4, 5, 1, 2, 3]
+```
