What is the main challenge in implementing a circular array?
Determining the starting index of the array
Managing the wrap-around behavior correctly
Handling the resizing of the array
Efficiently searching for elements in the array
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.
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?
Dynamic array (ArrayList, vector) to accommodate varying data sizes
Circular array to efficiently manage the fixed-size buffer
Standard array with shifting elements on each insertion
Sparse array to handle potentially sparse data
Rotating an array by 'k' positions to the right means:
Shifting each element 'k' positions to the right.
Shifting each element 'k' positions to the left.
Sorting the array in descending order.
Reversing the entire array.
In which scenario would using Insertion Sort for sorting an array be advantageous?
Sorting an array in reverse order.
Sorting an array with many duplicate elements.
Sorting an almost sorted array.
Sorting a very large array.
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 - 1
m + n
m + n - 1
m * n
You want to search for a target value in a sorted array with millions of elements. Which algorithm would generally be the fastest?
Jump Search
Binary Search
Interpolation Search
Linear Search
What data structure is commonly used to implement a sparse array efficiently?
Binary Tree
Linked List
Hash Table
Queue
Merge Sort is considered a stable sorting algorithm. What does 'stable' mean in this context?
The algorithm uses a fixed amount of memory regardless of the input size.
The algorithm maintains the relative order of elements with equal values after sorting.
The algorithm is not affected by the initial order of elements in the array.
The algorithm always takes the same amount of time to sort an array of a given size.
Which data structure is most suitable for implementing a sorted array with efficient insertion and deletion operations?
Array
Stack
