Practice 2 class GraphApp { Given a list of airline tickets represented by pairs of departure and arrival airports public List findItinerary(String[][] tickets) { // your code goes here } [from, to], reconstruct the itinerary in order. All of the tickets belong to a man who departs from JFK. Thus, the itinerary } must begin with JFK. Note: If there are multiple valid itineraries, Example 1: you should return the itinerary that tickets = [["MUC", "LHR"], ["JFK", "MUC"), ["SFO", "SJC"), ["LHR", "SFO"] has the smallest lexical order when Return ["JFK", "MUC", "LHR", "SFO", "SJC"]. read as a single string. For example, Example 2: the itinerary ["JFK", "LGA"] has a smaller lexical order than ["JFK", tickets = "LGB"]. [["JFK","SFO"],["JFK","ATL"],["SFO","ATL"],["ATL","JFK"),["ATL","SFO")]] All airports are represented by three Return ["JFK","ATL","JFK","SFO","ATL","SFO"]. capital letters (IATA code). Another possible reconstruction is ["JFK","SFO","ATL","JFK","ATL","SFO" You may assume all tickets form at least one valid itinerary.

Create a web form to help in creating simple random passwords. Your web form should have four text fields named Field1, Field2, Field3, and Field4, as well as “Reset” and “Submit” buttons. You need to create a separate PHP form-processing script that verifies that all four words are entered, that all of them contain only letters, and that all four are between 4 and 7 characters long. Once all of the words have been verified as correct, use the strtoupper() and str_shuffle() functions to produce four suggested jumbled sets of passwords using the words entered in the text fields Note: you need to perform the validation on the server side using PHP scripts. use the preg_match() function to check for letters
534470.3640684.qx3zqy7 Start This challenge activity consists of a series of auto-generated, randomized questions allowing unlimited submissions. You must correctly answer a question at each level before proceeding to the next level. The purpose of this first level is to familiarize yourself with how the autograder works. 1. Click the "Start" button to begin the challenge activity. 2. Copy the code provided and paste the code into the code window. The following code uses scnr.nextInt () to read in a value for variable numCarrots. Then, uses System.out.println () to output the value of numCarrots, followed by " carrots" and a newline. numCarrots = scnr.nextInt (); System.out.println (numCarrots + " carrots"); 3. Click the "Check" button to test your code. Our autograder automatically runs your program several times, testing different input values each time to ensure your program works for any values. An explanation is also provided. Note: You can only edit lines where the line number…
Create a form allowing you to add, subtract, divide and multiply numbers: Having created your window, first attach code to the buttons so that if you leave one of the numbers blank (or enter an invalid number) you get an error message: Arithmetic Arithmetic Error Choose first number: Choose second number: If, on the other hand, you enter valid numbers, you should see the answer appear in a label at the bottom of the window (set its Visibility property in XAML to Collapsed, then set it to Visiibility. Visible in code): Choose first number: 13 Choose second number: X X Arithmetic O T O 1 You haven't entered a valid number in this text box! X OK -0 Choose first number: 13 Choose second number: The answer is 1.86 X X
