You need to rotate an array by a very large 'k'. What optimization can be applied to improve efficiency?
Use a temporary array to store elements.
Calculate the effective rotation (k % n) where n is the array length.
No optimization is possible for large 'k'.
Sort the array before rotation.
Which of the following statements is TRUE about Quick Sort?
It performs poorly on already sorted arrays if the pivot selection is not optimized.
It always has a time complexity of O(n log n).
It is generally preferred over Merge Sort for arrays.
It is a stable sorting algorithm.
Which searching technique is most suitable for searching for a target element in a sorted array that is rotated at an unknown pivot point?
Binary Search
Interpolation Search
Linear Search
Depth First Search
What is a key characteristic of a circular array?
It conceptually wraps around, so the last element is followed by the first.
It allows direct access to any element in O(1) time.
It automatically sorts elements in ascending order.
It has a fixed size that cannot be changed.
In which scenario is a sparse array particularly useful?
Representing a matrix with mostly zero values
Storing a small array with frequent updates
Storing a large sorted array
Implementing a stack data structure
Interpolation search is most likely to outperform binary search when:
The target element is located near the middle of the array.
The array is unsorted.
The array is uniformly distributed.
The array size is small.
Which sorting algorithm has the least space complexity among Merge Sort, Quick Sort, and Heap Sort?
Merge Sort
Heap Sort
Quick Sort
You are searching for a target value in a 2D matrix where each row and column is sorted in ascending order. Which search algorithm is the most efficient?
Staircase Search
Binary Search on each row
Breadth First Search
Quick Sort is generally considered faster than Merge Sort in practice. What is one of the main reasons for this?
Quick Sort is a stable sorting algorithm, while Merge Sort is not.
Quick Sort has better space complexity than Merge Sort.
Quick Sort typically has smaller constant factors in its time complexity.
Quick Sort has better time complexity in all cases.
What is the time complexity of searching for a target value in a sorted array using binary search?
O(n log n)
O(n)
O(log n)
O(1)
