Sum, Count, and Reverse of Digits in Python...

1. Sum of digits Iterative Approach (Using While Loop) no = int(input("Enter No: ")) sum = 0 while no > 0: sum = sum + no % 10 no = no // 10 else: print(sum) Recursive Approach def sum_of_digits(no): if no == 0: # Base condition return 0 return (no % 10) + sum_of_digits(no // 10) no = int(input("Enter No: ")) result = sum_of_digits(no) print(result) Output 2. Count of digits Iterative Approach (Using While Loop) num = int(input("Enter number: ")) count = 0 while num > 0: num = num // 10 count +=
