how insertion sort occurs code example
Example 1: insertion sort
def insertionSort(arr):
for i in range(1, len(arr)):
key = arr[i]
j = i-1
while j >= 0 and key < arr[j] :
arr[j + 1] = arr[j]
j -= 1
arr[j + 1] = key
Example 2: program for insertion sort
def insertionSort(arr):
for i in range(1, len(arr)):
k = i
for j in range(i-1, -1, -1):
if arr[k] < arr[j]:
temp = arr[k]
arr[k] = arr[j]
arr[j] = temp
k = j
arr = [5, 2, 9, 1, 10, 19, 12, 11, 18, 13, 23, 20, 27, 28, 24, -2]
print("original array \n", arr)
insertionSort(arr)
print("\nSorted array \n", arr)
