Answer:
The best structures to create the following items are
- ARRAY
- HASHMAPS
- QUEUE
- SORTED LINK LISTS
Explanation:
The best structures to create the following items are:
- Array : for the storage of cards in a card game the best data structure to be used should be the Array data structure. this is because the size of the data ( 52 cards ) is known and using Array will help with the storing of the cards values in the Game.
- Hashmaps : Hashmap data structure should be implemented in online shopping cart this IS BECAUSE items can be easily added or removed from the cart therefore there is a need to map the Items ID or name to its actual database
- online waiting list are usually organised/arranged in a first-in-first-out order and this organization is best created using the queue data structure
- Sorted link lists is the best data structure used to create, store and manage online tickets. the sorted link data structure helps to manage insertions and deletions of tickets in large numbers and it also reduces the stress involved in searching through a large number of tickets by keeping the tickets in sorted lists
From scientists planing to share information across countries. Letters and the mail system took to long for certain situations.
I think that is the stupidest question ever (No offence). Of course you would use the one that doesn't need clearance or fee's. Like, Duh!
But I guess you also have to consider the quality of your pictures. If this physics lab write-up may be considered for some national competition (reusing the same paper for a different scenario) then I'd think that it's really up to you. Which one do you like the most?
To wrap things up, I honestly would choose the free one, but it always depends on your situation. How important is this project? Is this just homework for the teacher or is it going to be something bigger?
Answer: B. Personal Digital Assistant (PDA).
Although some of the other devices listed may have the capability of allowing the use of a digital pen, the use of the pen will be somewhat unnecessary. Let's take the personal computer and laptop for instance. In a personal computer and laptop we already have a mouse or track pad that can be used to navigate and select objects in the computer.
For the smart television, most smart televisions can actually be operated with gestures or voice command, the use of a digital pen will also not help due to the size of the screens of the televisions.
In the past we had some mobile phones that have a stylus as a pointer. This type of technology has now been change to touch screens that are more effective for the different types of mobile being produced now a days.
Most PDA's come with a screen that requires a small amount of pressure to activate commands. Digital pens also come with different functions that allow the device to draw, record audio, and even shortcut commands for these devices. These digital pens input are then converted by device and translated into computer language.
Answer:
The solution code is written in Java.
- public static void swapArrayEnds(int myArray[]){
- int lastIndex = myArray.length-1;
- int temp = myArray[0];
- myArray[0] = myArray[lastIndex];
- myArray[lastIndex ] = temp;
- }
Explanation:
First create the swapArrayEngs method that take one input array parameter (Line 1).
Since we need to swap the first and last element of the array, we need to get the first index and last index of the array. The first index is 0 and the last index can be calculated by subtracting the length of array from 1 (Line 2).
Next, we can create a temp variable to hold the value of the first element (Line 3). Then we use the lastIndex the get the value of last element and assign it to the first element of array (Line 4). Lastly, we assign the temp (holding the initial first element value) to the last element of array (Line 5).
