Flashcards
Selection Sort
Selection Sort
A sorting algorithm that sorts the elements in place, meaning it doesn't require additional memory to store the sorted elements. Its worst-case running time is quadratic (Θ(n^2)). This means the time it takes to sort increases significantly as the number of elements increases.
Merge Sort
Merge Sort
A sorting algorithm that follows the divide-and-conquer approach. It repeatedly divides the input array into two halves, sorts each half recursively, and then merges the sorted halves. Its time complexity is O(n log n) in all cases.
Insertion Sort
Insertion Sort
A sorting algorithm that has a linear running time (Θ(n)) in the best case when the input is already sorted. This means its speed increases linearly with the number of elements. Its average and worst-case time complexities are Θ(n^2).
