Your team is asked to develop ONE java program to compare the memory efficiency between: java.util.ArrayList and java.util.Vector

Hint #1: You can modify Quiz1.java to create your solution.

Hint #2: Do you how to count? Do you know how to find the difference?

Hint #3: Ava and Eva share a bank account which has $100 in it. After Ava took some money out, the account balance is $92. After Eva took some money out, the account balance is $87. How much did Ava take out? How much did Eva take out?
