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.

Check if a string is palindrome Program Code

# Check if a string is palindrome
text = input("Enter a string: ")

# Convert to lowercase for case-insensitive comparison
text_lower = text.lower()

# Remove spaces for multi-word phrases
clean_text = text_lower.replace(" ", "")

is_palindrome = True
length = len(clean_text)

for i in range(length // 2):
    if clean_text[i] != clean_text[length - 1 - i]:
        is_palindrome = False
        break

if is_palindrome:
    print(f'"{text}" is a palindrome')
else:
    print(f'"{text}" is NOT a palindrome')
