# Take array
n = int(input("Enter array size: "))
arr = []
for i in range(n):
arr.append(int(input(f"Element {i+1}: ")))
k = int(input("Enter rotation count: "))
k = k % n # Handle k > n
# Rotate
rotated = arr[-k:] + arr[:-k]
print("Rotated array:", rotated)Output
Enter array size: 5 Element 1: 1 Element 2: 2 Element 3: 3 Element 4: 4 Element 5: 5 Enter rotation count: 2 Rotated array: [4, 5, 1, 2, 3]
Use slicing to rotate array.
Key Concepts:
- Take last k elements
- Take first n-k elements
- Concatenate in rotated order
