What is the main challenge in implementing a circular array?
Handling the resizing of the array
Efficiently searching for elements in the array
Managing the wrap-around behavior correctly
Determining the starting index of the array
Interpolation search is most likely to outperform binary search when:
The array is unsorted.
The array is uniformly distributed.
The target element is located near the middle of the array.
The array size is small.
You need to implement a buffer that stores a fixed number of recent data points, discarding older data as new data arrives. Which array-based structure would be most appropriate?
Sparse array to handle potentially sparse data
Standard array with shifting elements on each insertion
Circular array to efficiently manage the fixed-size buffer
Dynamic array (ArrayList, vector) to accommodate varying data sizes
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?
Create a new array with exactly the required size.
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.
Merge Sort is considered a stable sorting algorithm. What does 'stable' mean in this context?
The algorithm always takes the same amount of time to sort an array of a given size.
The algorithm maintains the relative order of elements with equal values after sorting.
The algorithm uses a fixed amount of memory regardless of the input size.
The algorithm is not affected by the initial order of elements in the array.
What data structure is commonly used to implement a sparse array efficiently?
Hash Table
Binary Tree
Queue
Linked List
What is the time complexity of inserting an element into a Max Heap containing 'n' elements?
O(1)
O(n log n)
O(log n)
O(n)
What is the time complexity of rotating an array of size 'n' by 'k' positions in place?
O(n*k)
O(k)
You are designing a system to store a large sparse matrix where memory usage is critical. Which approach is most suitable?
Store the matrix in a text file and read it when needed.
Implement the sparse matrix using a hash table.
Use a standard 2D array.
Use a dynamic array and resize it as needed.
Which data structure is most suitable for implementing a sorted array with efficient insertion and deletion operations?
Stack
