Adjust the following code so the four errors below are non-present:

1. Stat.__repr__() : No declaration and implementation. Please know what is difference between __str__ and __repr__. (-0.5) 2. Stat.clear() : what is "s"? It cause error. (-0.5) 3. intlist.__repr__() : No declaration and implementation. (-0.5) 4. intlist.extend() : No declaration and implementation. (-0.5)

Code:
