Exam Relevance

The topic of sorting algorithms is frequently included in the syllabus for CBSE, State Boards, NEET, and JEE exams. Students can expect questions that require them to analyze the efficiency of different sorting methods or to apply these algorithms to solve problems. Common question patterns include multiple-choice questions that ask for the best sorting algorithm for a given scenario or to determine the time complexity of a specific algorithm.

Common Mistakes Students Make

• Confusing the time complexities of different sorting algorithms
• Overlooking the importance of space complexity in practical applications
• Misunderstanding the recursive nature of Merge Sort
• Failing to recognize the best-case, average-case, and worst-case scenarios for Quick Sort

FAQs

Question: What is the time complexity of Quick Sort?
Answer: The average time complexity of Quick Sort is O(n log n), while the worst-case time complexity is O(n²).

Question: How does Merge Sort differ from Quick Sort?
Answer: Merge Sort is a stable sorting algorithm that divides the array into halves, sorts them, and then merges them, while Quick Sort selects a pivot and partitions the array around it.
