Insertion Sort can be considered an incremental algorithm. What does this mean?
It requires the entire dataset to be present in memory
It performs better on smaller datasets
It divides the problem into smaller subproblems
It can handle data arriving in a continuous stream

Which statement BEST describes the significance of understanding sorting algorithms?
It's primarily a theoretical concept with little practical relevance.
All sorting algorithms perform equally well, so understanding them is unnecessary.
It's only essential for software engineers specializing in algorithm development.
It enables developers to choose the most suitable algorithm for a given task based on efficiency and data characteristics.
