Time Complexities of Sorting Algorithms

Algorithm | Time Complexity Best Average Worst Selection sort Ω(n^2) θ(n^2) O(n^2 Bubble Sort Ω(n) θ(n^2) O(n^2) Insertion Sort Ω(n) θ(n^2) O(n^2) Heap Sort Ω(n log(n)) θ(n log(n)) O(n log(n)) Quick sort Ω(n log(n)) θ(n log(n)) O(n^2) Merge Sort Ω(n log(n)) θ(n log(n)) O(n log(n)) Bucket Sort Ω(n+k) θ(n+k) O(n^2) Radix Sort Ω(nk) θ(nk) O(nk)
