1. Suppose that we want to add a method to a class of queues that will splice two queues together. This method adds to the end of a queue all items that are in a second queue (making the second queue empty). The header of the method could be as follows: public void splice(QueueInterface anotherQueue)
Write this method for the class ArrayQueue.
2. Add the method public boolean enqueueNoDuplicate(T item) which adds item if it is not already in the queue. If item is already present, no change to the queue takes place and the method returns false. Otherwise, the method returns true.

You will be given two character arrays of the same size, one will contain a number of ships. ships will move around the character array based on which way they are facing and the route they are on. routes are given in the other array. the route consists of '-' and '|' for straight paths, '\' and '/' for curves, and '+' for intersections. there are ships on these routes. ships always face a direction, '^' for up, '> ' for right, 'v' for down, and '< ' for left. any time the ships hit a '\' or a '/' it will turn as you would expect a ship to turn (e.g. a '^' that moves into a '/' will turn right). at an intersection, ships will always continue straight through. all ships move at the same speed, ships take turns moving and all ships move during one 'tick'. the one in the most top left goes first, followed by those to its right, then the ones in the next row. it iterates along the rows and then down the columns. each ship moves one space on its turn moving along the route. your function needs to return the position of the first collision between two ships and the number of ticks before the crash occurred.

What are procedures that keep a data base current

The file sales data.xlsx contains monthly sales amounts for 40 sales regions. write a sub that uses a for loop to color the interior of every other row (rows 3, 5, etc.) gray. color only the data area, columns a to m. (check the file colors in excel.xlsm to find a nice color of gray.)
