complexity of QuickSort in the average case?<br \/>\nA) O(1)<br \/>\nB) O(n)<br \/>\nC) O(n log n)<br \/>\nD) O(n^2)  <\/p>\n<p>Answer: C) O(n log n)  <\/p>\n<p>Explanation: QuickSort uses a divide-and-conquer approach, partitioning the array and sorting subarrays, leading to an average time complexity of O(n log n).  <\/p>\n<p>Question 2:<br \/>\nWhich data structure is best for implementing a priority queue?<br \/>\nA) Array<br \/>\nB) Linked List<br \/>\nC) Heap<br \/>\nD) Stack  <\/p>\n<p>Answer: C) Heap  <\/p>\n<p>Explanation: A heap is a complete binary tree that satisfies the heap property, making it efficient for priority queue operations like insertion and extraction of the minimum or maximum element.  <\/p>\n<p>Question 3:<br \/>\nIn a binary search tree, what is the worst-case time complexity for searching an element?<br \/>\nA) O(1)<br \/>\nB) O(log n)<br \/>\nC) O(n)<br \/>\nD) O(n log n)  <\/p>\n<p>Answer: C) O(n)  <\/p>\n<p>Explanation: In the worst case, a binary search tree can become skewed (like a linked list), requiring a traversal of all nodes, resulting in O(n) time complexity.  <\/p>\n<p>Question 4:<br \/>\nWhat does Dijkstra&#8217;s algorithm compute?<br \/>\nA) Shortest path in a graph with negative weights<br \/>\nB) Longest path in a graph<br \/>\nC) Shortest path from a source to all other vertices in a graph with non-negative weights<br \/>\nD) Minimum spanning tree  <\/p>\n<p>Answer: C) Shortest path from a source to all other vertices in a graph with non-negative weights  <\/p>\n<p>Explanation: Dijkstra&#8217;s algorithm uses a greedy approach to find the shortest paths from a starting node to all other nodes, but it requires non-negative edge weights.  <\/p>\n<p>Question 5:<br \/>\nWhich sorting algorithm is stable?<br \/>\nA) QuickSort<br \/>\nB) HeapSort<br \/>\nC) MergeSort<br \/>\nD) SelectionSort  <\/p>\n<p>Answer: C) MergeSort  <\/p>\n<p>Explanation: MergeSort is stable because it preserves the relative order of equal elements during the merging process.  <\/p>\n<p>Question 6:<br \/>\nWhat is the space complexity of an in-place quicksort?<br \/>\nA) O(1)<br \/>\nB) O(log n)<br \/>\nC) O(n)<br \/>\nD) O(n log n)  <\/p>\n<p>Answer: A) O(1)  <\/p>\n<p>Explanation: In-place quicksort uses a constant amount of extra space for the partitioning, though the recursion stack may use O(log n) space.  <\/p>\n<p>Question 7:<br \/>\nIn hash tables, what is a collision?<br \/>\nA) When two keys hash to the same index<br \/>\nB) When a key is not found<br \/>\nC) When the table is full<br \/>\nD) When resizing occurs  <\/p>\n<p>Answer: A) When two keys hash to the same index  <\/p>\n<p>Explanation: A collision happens when two different keys produce the same hash value, requiring resolution techniques like chaining or open addressing.  <\/p>\n<p>Question 8:<br \/>\nWhat is the primary advantage of using a linked list over an array?<br \/>\nA) Random access<br \/>\nB) Dynamic size<br \/>\nC) Faster insertion at the beginning<br \/>\nD) Cache efficiency  <\/p>\n<p>Answer: B) Dynamic size  <\/p>\n<p>Explanation: Linked lists can grow or shrink dynamically without needing to specify a size in advance, unlike arrays which have fixed sizes.  <\/p>\n<p>Question 9:<br \/>\nWhich traversal method of a binary tree visits nodes in the order: root, left, right?<br \/>\nA) In-order<br \/>\nB) Pre-order<br \/>\nC) Post-order<br \/>\nD) Level-order  <\/p>\n<p>Answer: B) Pre-order  <\/p>\n<p>Explanation: Pre-order traversal visits the root node first, then recursively traverses the left subtree, and finally the right subtree.  <\/p>\n<p>Question 10:<br \/>\nWhat is the time complexity of inserting an element into a sorted array?<br \/>\nA) O(1)<br \/>\nB) O(log n)<br \/>\nC) O(n)<br \/>\nD) O(n log n)  <\/p>\n<p>Answer: C) O(n)  <\/p>\n<p>Explanation: Inserting into a sorted array requires shifting elements to make space, which takes O(n) time in the worst case.  <\/p>\n<p>Question 11:<br \/>\nIn graph theory, what is a cycle?<br \/>\nA) A path that starts and ends at the same vertex<br \/>\nB) A tree with no loops<br \/>\nC) An edge with weight<br \/>\nD) A disconnected graph  <\/p>\n<p>Answer: A) A path that starts and ends at the same vertex  <\/p>\n<p>Explanation: A cycle is a path in a graph that begins and ends at the same vertex, forming a loop.  <\/p>\n<p>Question 12:<br \/>\nWhich algorithm is used to detect if a graph is bipartite?<br \/>\nA) Breadth-First Search (BFS)<br \/>\nB) Depth-First Search (DFS) with coloring<br \/>\nC) Kruskal&#8217;s algorithm<br \/>\nD) Both A and B  <\/p>\n<p>Answer: D) Both A and B  <\/p>\n<p>Explanation: Both BFS and DFS can be used to color the graph with two colors and check for conflicts, determining if it&#8217;s bipartite.  <\/p>\n<p>Question 13:<br \/>\nWhat is the purpose of memoization in dynamic programming?<br \/>\nA) To avoid recomputation by storing results of subproblems<br \/>\nB) To sort the array<br \/>\nC) To search for elements<br \/>\nD) To build a graph  <\/p>\n<p>Answer: A) To avoid recomputation by storing results of subproblems  <\/p>\n<p>Explanation: Memoization optimizes dynamic programming by caching the results of expensive function calls and reusing them.  <\/p>\n<p>Question 14:<br \/>\nIn a min-heap, where is the smallest element located?<br \/>\nA) At the root<br \/>\nB) At the leaves<br \/>\nC) At the rightmost node<br \/>\nD) Randomly  <\/p>\n<p>Answer: A) At the root  <\/p>\n<p>Explanation: A min-heap is a complete binary tree where the parent node is less than or equal to its children, so the smallest element is at the root.  <\/p>\n<p>Question 15:<br \/>\nWhat is the Knapsack problem an example of?<br \/>\nA) Greedy algorithm<br \/>\nB) Dynamic programming<br \/>\nC) Divide and conquer<br \/>\nD) Backtracking  <\/p>\n<p>Answer: B) Dynamic programming  <\/p>\n<p>Explanation: The 0\/1 Knapsack problem is solved using dynamic programming to evaluate all possible subsets and maximize value without exceeding weight.  <\/p>\n<p>Question 16:<br \/>\nHow many edges are in a complete graph with n vertices?<br \/>\nA) n<br \/>\nB) n(n-1)\/2<br \/>\nC) n^2<br \/>\nD) 2n  <\/p>\n<p>Answer: B) n(n-1)\/2  <\/p>\n<p>Explanation: A complete graph connects every pair of distinct vertices with a unique edge, resulting in n(n-1)\/2 undirected edges.  <\/p>\n<p>Question 17:<br \/>\nWhat is the time complexity of Floyd-Warshall algorithm?<br \/>\nA) O(1)<br \/>\nB) O(V + E)<br \/>\nC) O(V^3)<br \/>\nD) O(E log V)  <\/p>\n<p>Answer: C) O(V^3)  <\/p>\n<p>Explanation: Floyd-Warshall computes shortest paths between all pairs of vertices using a triple nested loop, leading to O(V^3) time complexity.  <\/p>\n<p>Question 18:<br \/>\nWhich of the following is not a divide-and-conquer algorithm?<br \/>\nA) MergeSort<br \/>\nB) QuickSort<br \/>\nC) BubbleSort<br \/>\nD) Binary Search  <\/p>\n<p>Answer: C) BubbleSort  <\/p>\n<p>Explanation: BubbleSort uses repeated swapping and is not a divide-and-conquer algorithm, unlike MergeSort, QuickSort, and Binary Search.  <\/p>\n<p>Question 19:<br \/>\nIn dynamic programming, what is the difference between top-down and bottom-up approaches?<br \/>\nA) Top-down uses memoization, bottom-up uses tabulation<br \/>\nB) Top-down is faster<br \/>\nC) Bottom-up uses recursion<br \/>\nD) There is no difference  <\/p>\n<p>Answer: A) Top-down uses memoization, bottom-up uses tabulation  <\/p>\n<p>Explanation: Top-down starts from the main problem and breaks it down with memoization, while bottom-up builds solutions from subproblems upward using tabulation.  <\/p>\n<p>Question 20:<br \/>\nWhat is the worst-case time complexity of the Ford-Fulkerson algorithm?<br \/>\nA) O(E)<br \/>\nB) O(VE^2)<br \/>\nC) O(V + E)<br \/>\nD) O(1)  <\/p>\n<p>Answer: B) O(VE^2)  <\/p>\n<p>Explanation: Ford-Fulkerson finds the maximum flow in a network, and in the worst case, it performs up to |f| augmentations, leading to O(VE^2) complexity for the Edmonds-Karp variant.<\/p>\n<\/div>\n<p><button id=\"copyquestionsBtn\" type=\"button\"
