  1. Learn how to check if a number is a strong number using Python programs with different approaches. A strong number is a number whose sum of the factorials of its digits is equal to the number itself.

  2. Problem Solution. 1. Take in an integer and store it in a variable. 2. Using two while loops, find the factorial of each of the digits in the number. 3. Then sum up all the factorials of the digits. 4. Check if the sum of the factorials of the digits is equal to the number.

    This program for a strong number allows the user to enter any positive integer. Next, this Python program checks whether the given number is a Strong Number or Not using the While Loop. Within this Python Program to find the Strong Number example, First, we are assigning the original value to the Temp variable. It helps us to preserve our original ...

    This program for strong numbers is the same as above. In this program, we replaced the While loop with For Loop.

    This strong number program is the same as the first example. However, we are using a built-in math function called factorial to find the factorial. This approach eliminates the Nested while loop.

    This program code uses list comprehension and the math factorial function to check and find the string number in Python.

    In this example, first, we have to import the reduce function from the functools and concat multiple lambda statements.
