suppose we'd like to access an element at an arbitrary index wihtin a linked list. what would be the efficiency?
To access an element at an arbitrary index within a linked list, the efficiency would be O(n).
Explanation: In a linked list, the elements are not stored in contiguous memory locations. Instead, each element or node has a pointer pointing to the next node. So, in order to access an element at an arbitrary index, we need to traverse the list from the first node until we reach the node at the desired index.
As each node in the list has only a pointer to the next node, it is not possible to access a node directly without traversing the entire list. Hence, to access an element at an arbitrary index within a linked list, the efficiency would be O(n).

The efficiency is O(n) to access an element at an arbitrary index wihtin a linked list.
Suppose we'd like to access an element at an arbitrary index within a linked list. When we look up an element in a linked list, we'll have to search through the entire list to find it. As a result, if the element is not in the first place, it will take a long time to discover.
As a result, in terms of time complexity, linked lists have O(n) efficiency. The linear search algorithm is used to access an element in a linked list. Here's how the algorithm works:
1. begin at the beginning of the list
2. Check whether the data in the node matches the target value.
3. If the data in the node matches the target value, return the node.
4. If the target value is not found, go to the next node in the list.
5. If the list is empty, the search is completed; otherwise, repeat steps 2 through 4. The time complexity of this algorithm is O(n) because it must search through the entire list to find the desired element.

describe a linear time algorithm to compute the neighbor degree for each vertex in an undirected graph.
The neighbor degree of a vertex in an undirected graph is the number of adjacent vertices to that vertex. To compute the neighbor degree for each vertex in an undirected graph, a linear time algorithm can be used.
The algorithm is as follows:
1. Initialize an array for the neighbor degree of each vertex.
2. Iterate through each vertex in the graph and check its adjacent vertices. For each adjacent vertex, increment the neighbor degree of that vertex in the array by one.
3. Repeat step 2 until all vertices have been visited and all neighbor degrees have been calculated.
This algorithm runs in linear time, as it only needs to visit each vertex and its adjacent vertices once.

a cashregister class contains an array list of coin objects. this is best described as an example of . group of answer choices cohesiveness aggregation inheritance association
The array list of coin objects in a cash register class is best described as an example of aggregation.
Aggregation is a mechanism for defining a one-to-many connection between objects, in which an object retains references to one or more instances of other objects. This indicates that the collection of objects is a 'component' of the overall system, and that it is dependent on the main object. However, the objects that make up the collection of objects may exist independently of the main object, and may still be used elsewhere in the system.
Hence, aggregation denotes a "has-a" connection between objects, as opposed to an "is-a" connection. An ArrayList is a class that is used to store a list of objects in Java. The list is ordered, and elements can be added to or removed from any position in the list. An ArrayList class implements the List interface, and so all of the methods of the List interface are available when using an ArrayList object. The most crucial point is that it supports dynamic memory allocation.Therefore the array list of coin objects in a cash register class is best described as an example of aggregation.

what are two protocols that are used by aaa to authenticate users against a central database of usernames and password? (choose two.)
The two protocols used by aaa to authenticate users against a central database of usernames and passwords, are TACACS+ or RADIUS. The correct answer B and E.
RADIUS (Remote Authentication Dial-In User Service) is a widely used protocol for managing user authentication, authorization, and accounting. It was originally developed for dial-up connections but is now used for other types of network connections as well.
TACACS+ (Terminal Access Controller Access-Control System Plus) is a protocol developed by Cisco that provides similar functionality to RADIUS, but with some additional features. TACACS+ separates the authentication, authorization, and accounting functions, allowing for more granular control over each.
