It deals with the study of shapes and spaces and how they can be related to each other. It is related to the study of networks and how they interact with each other.
This topology allows for the addition of new nodes without changing the overall design of the network. The star topology is also the easiest to troubleshoot and maintain, and can support a large number of nodes. Each node in the star topology is connected to a central switch or hub, which simplifies the management of the network and can help reduce costs.

Consider the following code segment, which is intended to print the sum of all elements of an array.
int[] arr = {10, 5, 1, 20, 6, 25};
int sum = 0;
for (int k = 0; k <= arr.length; k++)
{
sum += arr[k];
}
System.out.println("The sum is " + sum);
A runtime error occurs when the code segment is executed. Which of the following changes should be made so that the code segment works as intended?
(A) The for loop header should be replaced with for (int k = 0; k < arr.length; k++).
(B) The for loop header should be replaced with for (int k = 0; k <= arr.length; k--).
(C) The for loop header should be replaced with for (int k = 1; k <= arr.length - 1; k++).
(D) The statement in the body of the for loop should be replaced with sum += arr[0].
(E) The statement in the body of the for loop should be replaced with sum += arr[k - 1].
The for loop header should be replaced with for (int k = 0; k < arr.length; k++).
What is loop?Loop is a programming construct that allows a set of instructions to be repeated multiple times. It is one of the fundamental building blocks of programming and can be used to perform a wide variety of tasks. Loops can be used to iterate through collections of data, such as arrays and lists. They can be used to execute a set of instructions a specific number of times, or until a certain condition is met. Loops can also be used to create complex algorithms that would be difficult to achieve with traditional programming. Loops are an essential tool for any programmer and should be understood by all developers.

Consider an array of already sorted numbers. Which of the following algorithms would run in O(n) time?: *
A) MergeSort
B) InsertionSort
C) SelectionSort
LinearSearch - Linear search runs in O(n) time as it checks each element in the array sequentially until it finds the desired element.
What is Linear Search?Linear search, also known as sequential search, is a method for finding an element within a list. It sequentially checks each element of the list until a match is found or the whole list has been searched. Linear search runs in at worst linear time and makes at most n comparisons, where n is the length of the list. The time complexity of linear search algorithms, however, can vary depending on the number of elements being searched through and the size of the data set being searched. Linear search is a simple search algorithm and is often used as the starting point for more complex searching algorithms.
