Task 1 There are N houses along the street. Carbon filters are already installed in some of them. We would like to install filters in the remaining houses (those that do not possess them yet). Two types of filter, named 'a' and 'b', are being used. The filters work best if no three adjacent houses have the same type of filter. The houses are represented as a string of characters 'a', "b'and '?' (a' and "b' denote a house with a filter of a given type installed; "? represents a house with no filter yet). Your task is to make a plan of the filter types to be installed in the houses that do not yet have them Write a function class Solution ( public String solution(String S); } that, given a stringS of length N, returns a string that is the result of replacing each '?' in string S with an 'a' or a 'b' character and does not contain three identical consecutive letters (in other words, neither "aaa" nor "bbb" may occur in the processed string).
