  • 2. 

    There is only one algorithm for a specific task.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    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.

  • 3. 

    O(n) is in what time complexity?

    • Linear

    • Constant

    • Quadratic

    • Logatihmic

    Correct Answer
    A. Linear
    Explanation
    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.

    These are sorting algorithm except one:

    • Insertion

    • Merge

    • Linear

    • Selection

    Correct Answer
    A. Linear
    Explanation
    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.

  • 5. 

    O(n) time complexity is faster than O(1).

    • True

    • False

    Correct Answer
    A. False
    Explanation
    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).

  • 6. 

    This algorithm analysis specifies the Upper bound.

    • Big Oh

    • Big Omega

    • Big Theta

    Correct Answer
    A. Big Oh
    Explanation
    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:

  • 7. 

    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|

    • 2

    • 3

    • 4

    • 5

    Correct Answer
    A. 3
    Explanation
    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:

  • 8. 

    These are algorithm paradigms except one:

    • Divide and Conquer

    • Backtracking

    • Searching

    • Greedy

    Correct Answer
    A. Searching
    Explanation
    The given options represent different algorithm paradigms. Divide and Conquer, Backtracking, and Greedy are all well-known algorithm paradigms used in problem-solving. Searching, on the other hand, is not considered an algorithm paradigm but rather a specific problem-solving technique used within various algorithm paradigms. Therefore, the correct answer is Searching.

    Rate this question:

  • 9. 

    This algorithm analysis evaluates and algorithm in its best case.

    • Big Oh

    • Big Omega

    • Big Theta

    Correct Answer
    A. Big Omega
    Explanation
    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.

    If f(x) =  x +1   the Big Oh is O(1)

    • True

    • False

    Correct Answer
    A. False
    Explanation
    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.

    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 

    • 2

    • 4

    • 5

    • 7

    Correct Answer
    A. 5
    Explanation
    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.

    What operations can we get from the following line? (Wrong choices will be deducted from your scores) if x > 2 and i = j+1 

    • Assignment

    • Indexing

    • Return

    • Addition

    • Comparison

    • Subtraction

    • Call

    Correct Answer(s)
    A. Assignment
    A. Addition
    A. Comparison
    Explanation
    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:

  • 14. 

    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|

    • 3

    • 9

    • 2

    • 7

    Correct Answer
    A. 7
    Explanation
    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.

    What operations can we get from the following line ? (Wrong choices will be deducted from your scores) for i = 1 to  (n-1) 

    • Assignment

    • Indexing

    • Return

    • Addition

    • Subtraction

    • Comparison

    • Call

    Correct Answer(s)
    A. Assignment
    A. Addition
    A. Subtraction
    A. Comparison
    Explanation
    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.
