Rotate list to the right by k positions Dry Run in PYTHON

Rotate list to the right by k positions is an interactive PYTHON dry run visualizer from the Lists programs section. Study the source code, then use the execution controls to follow each step, variable update, highlighted line, and console output.

This page provides a browser-based dry run with source-code highlighting, auto-scroll, voice narration controls, and execution output for learning the program step by step.

Rotate list to the right by k positions Program Code

# Rotate list right by k positions
arr = [1, 2, 3, 4, 5, 6, 7]
k = 3
print(f"Original: {arr}, rotate right by {k}")

# Method 1: Slicing
k = k % len(arr)
rotated = arr[-k:] + arr[:-k]
print(f"Using slicing: {rotated}")

# Method 2: Manual rotation (pop from end, insert at front)
arr2 = [1, 2, 3, 4, 5, 6, 7]
for _ in range(k):
    last = arr2.pop()
    arr2.insert(0, last)
print(f"Manual rotation: {arr2}")
