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

Write a method called removeInRange that accepts four parameters: an ArrayList of integers, an element value, a starting index,

Murrr4er [49]

Answer:

public static void removeInRange(List<Integer> list, int value, int start, int end) {

for (int i = end - 1; i >= start; i--) {

if (list.get(i) == value) {

list.remove(i);

}

System.out.println(list);

}

Explanation:

- Create a method named removeInRange that takes four parameters, a list, an integer number, a starting index and an ending index

- Inside the method, initialize a for loop that iterates between starting index and ending index

- If any number between these ranges is equal to the given value, then remove that value from the list, using remove method

- When the loop is done, print the new list

.An algorithm specifies the actions to be executed. True False

steposvetlana [31]

Answer:

True.

Explanation:

An algorithm for a problem provides the set of instructions that are required to solve a problem.It does not provide the full code.It is like an abstract solution of a problem.It is just like a recipe for cooking a dish.It will not cook food for you but can tell you how to cook.

Since it provides the action to be executed hence the answer is True.

Please check my answers! (Java)

I think only II contains an error.

Tricky because, syntactically, all three are correct I.M.O.

However, if the goal is to iterate as many times as lotNumLength, then statement II loops one time too many. This is known as an off-by-one error.

You have been asked to decouple an application by utilizing SQS. The application dictates that messages on the queue can be deli

LuckyWell [14K]

Answer:

Option B is the correct option.

Explanation:

When using SQS the user request to separate a query. The specification specifies that updates on the list may have been transmitted multiple times, but it must be transmitted throughout the sequence in which they appeared, and therefore should require secure, repetitive queue polling.

So, They configure a First In First Out SQS queue and allow long-polling which is suitable for AWS services.

What should the shutter speed be on the camera? A. 1/30 B. 1/50 C. 1/60 D. 1/15

11Alexandr11 [23.1K]

Answer:

C. 1/60

Explanation:

Shutter speed is most commonly measured in fractions of a second, like 1/20 seconds or 1/10 seconds. Some high-end cameras offer shutter speeds as fast as 1/80 seconds. But, shutter speeds can extend to much longer times, generally up to 30 seconds on most cameras.

But in this case C. 1/60 is the answer.
