**Simple python programs to practice:**

1) Write a Python function

**Factorial(n)**which returns the factorial of the given number(n).

2) Write a Python function,

**Square(num)**which returns the square of the given number(num).

3) Write a Python function,

**Sum(n)**which returns the sum of first n numbers.

4) Write a Python function,

**Palindrome(num)**that accepts an integer num as input and returns true/false based on condition.

Ex: num = 12321 ---> output = 12321 ----> then given number is palindrome.

5) Write a Python function,

**check_strong_number(num)**that accepts a positive as input, and return true/false based on condition.

- A number is said to be a Strong number if the sum of the factorial of each digit is equal to the given number.
