Selection sort is a sorting algorithm that selects the smallest element from an unsorted list in each iteration and places that element at the beginning of the unsorted list.
def selectionSort(array, size):
for step in range(size):
min_idx = step
for i in range(step + 1, size):
# to sort in descending order, change > to < in this line
# select the minimum element in each loop
if array[i] < array[min_idx]:
min_idx = i
# put min at the correct position
(array[step], array[min_idx]) = (array[min_idx], array[step])
data = [-2, 45, 0, 11, -9]
size = len(data)
selectionSort(data, size)
print('Sorted Array in Ascending Order:')
print(data)
