WebThe selection sort algorithm sorts an array by performing selection sorting on the array till it gets sorted. Selection sort has a mechanism where the element is searched by traversing from start till the end by replacing the smallest element found within the array. WebDec 6, 2024 · Selection sort is a sorting algorithm that uses in-place comparison to rearrange elements in several rounds or iterations. In each round, the algorithm selects the smallest element from the given list or array and places the smallest element at the beginning of the list by swapping after comparison from every element of the list or array.
