Public static int[] sortthisarray-new int[{45, 78, 92, 21, 62, 8, 2, 81, 9, 25, 98}; if you have a method that selects the best pivots for quicksort (do not use the default pivot selection method), indicate what pivots would be selected and provide the values in sort thisarray (provided above) once the final position for a pivot has been determined. problem 8: public static int 1001); sort thisarray = new int[]{1001, 1101, 11101, , 0011, 0111, perform binary radix sort (ascending order) on sortthisarray, provided above, by listing the contents of the array after each bucketization. problem 9: explain why the time complexity for merge sort o(nlogn)? using the recurrent expression for merge sort in your explanation. problem 10: perform counting sort on an array containing the following numbers: 1, 6, 7, 8, 2, 6, 7,9, 9, 3, 8, 5, 0, 1, 4 (from index 0 to 14). the numbers are integers that can take values between 0 and 9 inclusively. indicate where in the final sorted array each number will end up. the 1 in index 0 should end up in a different index than the 1 in index 13.

File account.java (see previous exercise) contains a definition for a simple bank account class with methods to withdraw, deposit, get the balance and account number, and return a string representation. note that the constructor for this class creates a random account number. save this class to your directory and study it to see how it works. then write the following additional code: 1. suppose the bank wants to keep track of how many accounts exist. a. declare a private static integer variable numaccounts to hold this value. like all instance and static variables, it will be initialized (to 0, since it’s an int) automatically. b. add code to the constructor to increment this variable every time an account is created. c. add a static method getnumaccounts that returns the total number of accounts. think about why this method should be static - its information is not related to any particular account. d. file testaccounts1.java contains a simple program that creates the specified number of bank accounts then uses the getnumaccounts method to find how many accounts were created. save it to your directory, then use it to test your modified account class.
