Which of the following is a real-world application of sorting in databases?
Query optimization for faster retrieval of results.
Data encryption for enhanced security.
Natural language processing for text analysis.

Which statement BEST describes the significance of understanding sorting algorithms?
It's primarily a theoretical concept with little practical relevance.
It enables developers to choose the most suitable algorithm for a given task based on efficiency and data characteristics.
All sorting algorithms perform equally well, so understanding them is unnecessary.
It's only essential for software engineers specializing in algorithm development.
What is the primary operation used in Insertion Sort to place an element in its correct position?
Merging
Swapping
Shifting
Comparison
Why is Insertion Sort not preferred for large datasets?
It is not a stable sorting algorithm
It has a high space complexity
It is difficult to implement
Its time complexity is quadratic in the worst case
In what real-world scenario might you encounter the need for a sorting algorithm?
Displaying search results in order of relevance.
Compressing an image file to reduce its size.
Generating random numbers within a specified range.

Sorting algorithms can be broadly classified into two categories. What are they?
In-place and Out-of-place
Comparison-based and Non-comparison-based

Why is understanding the time and space complexity of sorting algorithms crucial?
To estimate the efficiency and resource usage of an algorithm for different input sizes.
To determine the exact number of comparisons and swaps performed by an algorithm.
To convert between different sorting algorithms.
To predict the output of a sorting algorithm without actually executing it.
When does Insertion Sort exhibit its worst-case time complexity?
