**Selection sort algorithm -**In this article, we will learn about another sorting algorithm - Selection sort. Just like Bubble sort, time complexity of this algorithm is O(n^2) and space complexity being O(1).

#### Selection Sort Algorithm

i = 0 while i < length(array) begin search for minimum element in the list array[i:] exchange the minimum element with array[i] increment i by 1 end

#### Example

Consider the following list-

**Iteration 1:**

**Iteration 2:**

**Iteration 3:**

**Iteration 4:**

**Iteration 5:**

**Iteration 6:**

**Iteration 7:**

**Iteration 8:**

#### Python Implementation:

def selection_sort(array): n = len(array) for i in range(n): # Index of smallest element min_index = i for j in range(i+1, n): if array[j] < array[min_index]: min_index = j array[min_index], array[i] = array[i], array[min_index] my_array = [5, 3, 7, 1, 4, 8, 2, 6] selection_sort(my_array) print my_array

**Output:**

[1, 2, 3, 4, 5, 6, 7, 8]
