Range Selection of Unsorted Array

Write a method findRanks in Java that accepts an unsorted array of integers vals, and a starting and ending rank start and end, numbering ranks from 0, and returns an unsorted (any order is acceptable) array containing the lo-th through the hi-th elements, inclusive, of vals. int[] findRanks(int[] vals, int lo, int hi) For instance, if vals contains 10 elements as shown: 4 2 9 11 9 19 21 14 16 8 then the call findRanks(vals, 2, 5) will return an array containing the 3rd (remember we number from 0) through 6th items in vals (e.g. 8 9 11 9).

Median of Three Worst Case Scenario

Suppy an array containing integers 1 through 12 such that a quicksort algorithm using median of three will recurse to 6 levels, counting the top level as 0; showing that even with median of three, quicksort has worst case performance of O(n^2). The pivot is then moved to the end and the partition is performed, then after the partition, the pivot moves to its rightful place. Median of three: on the range [p, r], choosing as the split value the median of vals[p], vals[r], and vals[(p+r)/2].

data validations

I need help on how to validate these data in visual basic.net: 1. the password must not be same as employee ID and must contain 4-6 characters 2. email must ba a valid one 3. name and address fields cannot be left blank 4. maxium score must be postive number between 1 and 100 5. number of students must be postive integer Assuming password, email, name and address, max score, and number of students are textboxes. If the each rule are broken then a messagebox will appear. Thank you.

Calculator

Looking for mortgage program to display 3 mortgage loans: 7 year at 5.35%, 15 year at 5.5 %, and 30 year at 5.75%. Use an array for the different loans Display the mortgage payment amount for each loan. Non-graphical user interface. Insert comments in the program to document the program. Build on this if possible using an array: import java.math.*; import java.text.*; //class BuyaHomeCalculator class BuyaHomeCalculator { public static void main(String arguments[]) { //Program Variables double term = 360; double interestRate = 0.0575; double loan = 200000; double monthlyRate = (interestRate/12); //Discount facto... click for more
