• In python, please produce a simple recurisve function. Attached is the test case.
• remove_Sub(s, sub) - The parameters s and sub are strings that contain at least one character. This function will return a string where all occurrences of sub are removed in the order it appears in the string s (see example test below for an interesting case).

Example test assert remove_Sub("Lolololol", "lol") == "Loo" # The first "lol" is removed, which reduces the string # to: "Loolol". Then the 2nd "lol" is removed, which # reduces the string to: "Loo"
