Substring Count
Counting substrings is useful when looking for repeated fragments in text or code. Write a function count_substring that receives a string s and a substring sub. Return the number of non-overlapping occurrences of sub in s. For example, in aaaa, the substring aa appears twice because the matched positions must not overlap.
