The method is given a list of strings called list and a string value . Implement it so that it returns the index of the last occurrence of value in list. For example, given ["cat", "dog", "goose", "dog", "cat"] and "dog", this method would return 3 (the index where the second occurrence of "dog" appears). If list does not contain the value, this method should return - 1. For example, given ['cat", "dog", "goose", "dog", "cat"] and "salamander", this method would return \( -1 \). Hint: Remember that when comparing Strings you must use string1. equals(string 2 ), not string1 == string2 .
