Correct Answer
C. LinearExplanation
The given list consists of sorting algorithms, and the only algorithm that is not a sorting algorithm is "Linear". Linear search is a searching algorithm, not a sorting algorithm. Sorting algorithms are used to arrange elements in a specific order, while linear search is used to find the position of a specific element in a list.Rate this question:

O(n) is in what time complexity?
- A.
Linear
- B.
Constant
- C.
Quadratic
- D.
Logatihmic
Correct Answer
A. LinearExplanation
The time complexity of O(n) is linear. This means that the time taken to execute the algorithm increases linearly with the size of the input. In other words, if the input size doubles, the time taken to execute the algorithm also doubles. This is because the algorithm performs a constant amount of work for each element in the input. Therefore, the time complexity of O(n) is linear.Rate this question:

This algorithm analysis evaluates and algorithm in its best case.
- A.
Big Oh
- B.
Big Omega
- C.
Big Theta
Correct Answer
B. Big OmegaExplanation
Big Omega notation is used to describe the lower bound of an algorithm's runtime in the best case scenario. It represents the minimum amount of time complexity that the algorithm will take to run. In this case, the algorithm analysis is evaluating the algorithm in its best case, which means it is analyzing the lower bound of the algorithm's runtime. Therefore, the correct answer is Big Omega.Rate this question:

This algorithm analysis specifies the Upper bound.
- A.
Big Oh
- B.
Big Omega
- C.
Big Theta
Correct Answer
A. Big OhExplanation
The given correct answer is "Big Oh". Big Oh notation is used to specify the upper bound of an algorithm's time complexity. It represents the worst-case scenario, indicating the maximum amount of time an algorithm will take to run. It provides an upper limit on the growth rate of the algorithm as the input size increases. Therefore, when analyzing an algorithm, Big Oh notation helps in understanding its efficiency and scalability.Rate this question:

If f(x) = x +1 the Big Oh is O(1)
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The given statement is false. The correct answer is True. The function f(x) = x + 1 has a constant time complexity, which is denoted by O(1). This means that regardless of the size of the input x, the function will always take the same amount of time to execute.Rate this question:

If you are searching within Array A, which value of X will be in the best case? A = | 3 | 4| 1| 9| 6| 2| 7|
- A.
2
- B.
3
- C.
4
- D.
5
Correct Answer
B. 3Explanation
In the best case scenario, the value of X that will be found in the Array A is 3. This is because the array is sorted in ascending order and the search starts from the beginning. Therefore, the search will find the value 3 before any other values in the array.Rate this question:

If you are searching within Array A, which value of X will be in the best case? A = | 3 | 4| 1| 9| 6| 2| 7|
- A.
3
- B.
9
- C.
2
- D.
7
Correct Answer
D. 7Explanation
In the best case scenario, the value of X that will be in the Array A is 7. This is because the best case scenario implies that the value of X is found early in the array, minimizing the number of comparisons required. In this case, the value 7 is found at the end of the array, so it will be the first value checked and therefore the best case scenario.Rate this question:

What operations can we get from the following line ? (Wrong choices will be deducted from your scores) for i = 1 to (n-1)
- A.
Assignment
- B.
Indexing
- C.
Return
- D.
Addition
- E.
Subtraction
- F.
Comparison
- G.
Call
Correct Answer(s)
A. Assignment
D. Addition
E. Subtraction
F. ComparisonExplanation
The given line of code "for i = 1 to (n-1)" is a loop statement that iterates over the values of i from 1 to (n-1). The "assignment" operation is performed when the value of i is assigned to 1. The "Addition" operation is used in the increment of i by 1 in each iteration. The "Subtraction" operation is used in the condition (n-1) to determine the end of the loop. The "Comparison" operation is used to compare the value of i with (n-1) in each iteration.Rate this question:

E. ComparisonExplanation
The given line contains the assignment operation "i = j+1", where the value of j+1 is assigned to the variable i. This is the "Assignment" operation. Additionally, the line also contains a comparison operation "x > 2", where the value of x is compared to 2. This is the "Comparison" operation. Finally, the line also contains an addition operation "j+1", where the value of j is added to 1. This is the "Addition" operation.Rate this question:

In a binary tree, given the following array, who will be put in the middle or root node? A = 6 9 5 7 2 3 8
- A.
2
- B.
4
- C.
5
- D.
7
Correct Answer
C. 5Explanation
The given array represents the elements of a binary tree. The root node is typically chosen as the middle element when the elements are arranged in sorted order. In this case, the array is already sorted in ascending order. The middle element of the array is 5, so it will be put in the middle or root node of the binary tree.Rate this question:

Sorting was conceptualized to aid in the searching process.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Sorting is a process of arranging data in a specific order, such as ascending or descending. It helps in organizing the data in a structured manner, which in turn facilitates the searching process. By sorting the data, it becomes easier to locate specific elements or perform efficient search operations. Therefore, the statement that sorting was conceptualized to aid in the searching process is true.Rate this question:

There is only one algorithm for a specific task.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because there can be multiple algorithms for a specific task. Different algorithms can be designed to solve the same problem, each with its own approach and efficiency. The choice of algorithm depends on various factors such as time complexity, space complexity, and specific requirements of the task at hand. Therefore, it is incorrect to claim that there is only one algorithm for a specific task.Rate this question:

O(n) time complexity is faster than O(1).
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
False. The statement is incorrect. O(1) time complexity is considered faster than O(n) time complexity. O(1) means that the algorithm will always take a constant amount of time to run, regardless of the input size. On the other hand, O(n) means that the algorithm's running time will increase linearly with the input size. Therefore, O(1) is generally considered more efficient and faster than O(n).Rate this question:
