Problem C. (iv points) searching ior a string This problem will exercise your ability with looping constructs over multiple strings. The goal of this function is given three strings A, B, and C. Find all of the characters that are in both strings A and B, but not in String C. Write one function called character_search(string_a, string_b, string_c) The function will take in three parameters string_a, string_b, and string_c all of which will be string objects. The function will build and return a string containing all of the characters that are in string_a and string_b, but which are not in string_c. The output string should have the letters in the same order they appear in string__. Hints: - You may assume that no character appears in a single string multiple times. Constraints: - You are not allowed to use the Python set intersection, the in keyword to check for inclusion, or anything similar, to trivialize the problem. This should be done only with strings and loops. - The in keyword when used as required by for loop syntax is acceptable You are welcome to add an if _ name _ = _ main _ block and test cases for this and all functions in this assignment but this is not required. Examples (text in bold is returned): character_search ("ABCDEFGHI", "ABCD", "abCd") Hints: - You may assume that no character appears in a single string multiple times.
