Implement a BlockedList class that implements the List interface. You may use any of the classes in JCF or in the textbook code. The constructor for this class takes an integer block size b and the implementation should have these performance characteristics: get(i) and set(i,x) should run in O(1) time per operation add(i,x) and remove(i) should run in O(b+ min{i, n-i}/b) amortized time per operation. THIS IS DATA TYPE SHOULD CONTAINA A SINGLE ARRAYDEQUE THATS STORES ARRAYDEQUES OF SIZE B(BLOCK SIZE)
