You want to search for a target value in a sorted array with millions of elements. Which algorithm would generally be the fastest?
Linear Search
Interpolation Search
Jump Search
Binary Search
Quick Sort is generally considered faster than Merge Sort in practice. What is one of the main reasons for this?
Quick Sort has better time complexity in all cases.
Quick Sort is a stable sorting algorithm, while Merge Sort is not.
Quick Sort typically has smaller constant factors in its time complexity.
Quick Sort has better space complexity than Merge Sort.
Which of the following is NOT a valid approach for array rotation?
Juggling Algorithm
Merge Sort Algorithm
Reversal Algorithm
Block Swap Algorithm
In merge sort, what is the maximum number of comparisons required to merge two sorted subarrays of size 'm' and 'n' into a single sorted array of size 'm+n'?
m + n
m + n - 1
m * n - 1
m * n
You are designing a system to store a large sparse matrix where memory usage is critical. Which approach is most suitable?
Use a dynamic array and resize it as needed.
Implement the sparse matrix using a hash table.
Use a standard 2D array.
Store the matrix in a text file and read it when needed.
A dynamic array is used to store a growing dataset. When the array reaches its capacity and needs to resize, what is the common strategy to ensure amortized constant time complexity for appending elements?
Use a linked list instead of resizing the array.
Double the size of the array when full.
Increase the array size by a fixed constant when full.
Create a new array with exactly the required size.
In which scenario is a sparse array particularly useful?
Storing a large sorted array
Representing a matrix with mostly zero values
Storing a small array with frequent updates
Implementing a stack data structure
In the context of searching algorithms, what does the term 'adaptive' refer to?
Algorithms that adjust their strategy based on previous search results.
Algorithms with a constant time complexity.
Algorithms that use divide-and-conquer techniques.
Algorithms that can handle unsorted data.
What is the time complexity of rotating an array of size 'n' by 'k' positions in place?
O(n)
O(n*k)
O(1)
O(k)
In which scenario would using Insertion Sort for sorting an array be advantageous?
Sorting an almost sorted array.
Sorting a very large array.
Sorting an array in reverse order.
Sorting an array with many duplicate elements.
