Mutation Removal in Genome

Given a string genome representing the nucleotides in an organism and a character mutation representing the mutated nucleotide. The task is to determine the earliest time after which no removals are possible. Example: If genome = "luvzliz" and mutation = 'z', the process of removal is described as following: The mutated nucleotide removes the other nucleotides to its left, removing one nucleotide at a time per unit time until no more removals are possible. Return the earliest time. Input A string genome and a character mutation. Output An integer representing the time after which no more nucleotides can be removed. Example Input: genome = "aa", mutation = 'a' Output: 1 Input: genome = "luvzliz", mutation = 'z' Output: 3 Example Input luvzliz z
