WebComplexity Selection sort takes time and space. The main time cost comes from scanning through the array to find the next smallest item. We do that n times. The first time, we'll be looking at n elements, the next time it'll be n - 1 elements, and so on, until we're left with just one element. Adding all those up, we've got WebFeb 16, 2024 · Selection sort has a quadratic time complexity because it uses nested loops to sort the elements in the list. The inner loop iterates over the unsorted portion of the list, while the outer loop iterates over the entire list. This as a result gets a running time of O(n × n) = O(n 2). Best case Time Complexity of Selection Sort: O(n)

Time and Space Complexities of Sorting Algorithms Explained

WebIn selection sort, the minimum element is selected from the array and swap with an element which is at the beginning of the unsorted sub array. The time complexities in best case and worst case are O(n) and O(n2) respectively. The time complexity in both best and worst cases is O(n 2). It is not an efficient sorting technique.
