Web2 hours ago · 1. First, we get a number as input from the user. 2. Next, we initialize a variable factorial and set its value as 1. 3. We make use of the for loop to iterate from 1 to the input number. 4. While looping we multiply each number by the current value of factorial and store it back in factorial. 5. WebJul 11, 2024 · Double factorial of a non-negative integer n, is the product of all the integers from 1 to n that have the same parity (odd or even) as n. It is also called as semifactorial of a number and is denoted by !!. For example, double factorial of 9 is 9*7*5*3*1 which is 945. Note that, a consequence of this definition is 0!! = 1.
