WebJun 15, 2024 · In the selection sort technique, the list is divided into two parts. In one part all elements are sorted and in another part the items are unsorted. At first, we take the maximum or minimum data from the array. After getting the data (say minimum) we place it at the beginning of the list by replacing the data of first place with the minimum data. WebAug 29, 2024 · Finally, selection sort is greatly outperformed on larger arrays by Θ(n log n) divide-and-conquer algorithms such as mergesort.

WebEven though JavaScript has a built-in sorting method, sorting is a great example of how there may be many ways to think about the same problem, some perhaps better than others. Understanding sorting is a traditional first step towards mastery of … WebSelection Sort sets the first index as sorted, and shifts each minimum value into the correct position by finding the lowest value on the sorted side of the array at indices lower than the current index. Selection Sort finds the lowest value in an array and shifts all elements to the right of that value.
