Q2. Factorial coding q
Ans. 
Factorial coding involves encoding numbers based on their factorial representation, useful in combinatorial problems.
• Factorial of a number n (n!) is the product of all positive integers up to n. Example: 5! = 5 × 4 × 3 × 2 × 1 = 120.

• Factorial coding can represent numbers uniquely using their factorial base. Example: 10 can be represented as 3! + 2! + 1!.

• It is often used in combinatorial algorithms and data structures, ...read more

Q2. One programming question factorial of 5
Ans. 
The factorial of a number is the product of all positive integers up to that number. For 5, it's 5! = 5 x 4 x 3 x 2 x 1.
• Factorial is denoted by 'n!'. For example, 5! = 5 x 4 x 3 x 2 x 1.

• Factorial of 0 is defined as 1: 0! = 1.

• Factorials grow rapidly: 6! = 720, 7! = 5040.

• Factorial can be calculated using recursion or iteration.
