public static void main(String[] args) { // (1) Use map to implement the following behavior (described in Python). i.e given a List create a List of the hashes of the objects. // names = ['Mary', 'Isla', 'Sam'] // for i in range(len(names)): // names[i] = hash(names[i]) // (2) Use foldL to calculate the sum of a list of integers. // i.e write a method: int sum(List l) // (3) Use foldR to concatenate a list of strings i.e write a method // String s (List l)
