New test cases added, rejudging my ACed JAVA solution to TLE

    A pretty large test case is added, making my previously ACed JAVA solution TLE.
    I guess it's due to the frequent stack operations (reallocation memory).
    I worked around this by using ArrayList to simulate the Stack and specify the init capacity to avoid memory reallocation. It works.

    Not sure if there is better solution.
