Program for Reversal algorithm for array rotation

def rverseArray(arr, start, end):

while (start < end):

temp = arr[start]

arr[start] = arr[end]

arr[end] = temp

start += 1

end = end-1

def leftRotate(arr, d):

n = len(arr)

rverseArray(arr, 0, d-1)

rverseArray(arr, d, n-1)

rverseArray(arr, 0, n-1)

def printArray(arr):

for i in range(0, len(arr)):

print (arr[i])

arr = [1, 2, 3, 4, 5, 6, 7]

leftRotate(arr, 2)

printArray(arr)

Program to Split the array and add the first part to the end

def splitArr(arr, n, k):

for i in range(0, k):

x = arr[0]

for j in range(0, n-1):

arr[j] = arr[j + 1]

arr[n-1] = x

arr = [12, 8, 10, 11, 52, 36]

n = len(arr)

position = 2

splitArr(arr, n, position)

for i in range(0, n):

print(arr[i], end = ' ')
