Which of the following correctly describes the primary difference between Insertion Sort and Selection Sort?
Which of the following correctly describes the primary difference between Insertion Sort and Selection Sort?
- Insertion Sort builds the sorted array incrementally, while Selection Sort makes comparisons on a single element and then makes a swap. (correct)
- Insertion Sort is more efficient for large datasets, while Selection Sort is better for smaller datasets.
- Insertion Sort uses a 'while' loop, while Selection Sort uses a 'for' loop.
- Insertion Sort sorts elements in place, while Selection Sort requires additional space.

Bubble Sort
Bubble Sort
A sorting algorithm that compares adjacent elements and swaps them if they are in the wrong order.
Insertion Sort
Insertion Sort
Builds a sorted array by repeatedly picking the next element and inserting it into the correct position.
Selection Sort
Selection Sort
Divides the list into sorted and unsorted regions, selecting the smallest element from the unsorted to move to sorted.

Study Notes
Sorting Algorithms
-
Bubble Sort: Compares adjacent elements, swapping them if they're out of order. Repeats until no swaps are needed.
-
Insertion Sort: Builds the sorted array one element at a time. It repeatedly picks the next element and inserts it into the correct position within the sorted portion of the array.
-
Selection Sort: Divides the list into a sorted and unsorted region. Selects the smallest element from the unsorted region and moves it to the sorted region. Repeatedly selects the smallest and moves it to the sorted region.
-
Quick Sort: Selects a 'pivot' element, partitions the array into elements less than and greater than the pivot. Recursively applies this to subarrays.
-
Merge Sort: Divides the array into two halves, recursively sorts each half, and then merges the sorted halves to produce a single sorted array. Iterates and compares elements to merge into sorted order. Divides arrays repeatedly until they are of size 1. Then merges adjacent sorted arrays.
