Solution 1: Factorial Calculation using Loops Code: importjava.util.Scanner;publicclassFactorialUsingLoop{public static void main(String[]args){Scanner scanner=new Scanner(System.in);//Taking userinputSystem.out.print("Enter a number: ");intnum=scanner.nextInt();//Initializing factorial value to1...
Here, we are going to implement logic to find factorial of given number in Python, there are two methods that we are going to use 1) using loop and 2) using recursion method.
publicstaticlongfactorialRecursive(longn){returnn==1?1:n*factorialRecursive(n-1);} 4. Calculate Factorial using Stream API We can useJava Stream APIto calculate factorial in the most effective manner as below. publicstaticlongfactorialStreams(longn){returnLongStream.rangeClosed(1,n).reduce(1,(...
The weakness of this design from a Java perspective should be obvious: it does not allow us to select the algorithm we wish to use at runtime, which was a major design feature we were striving for. (I mean, after all, if our new program has different constraints, we should be able t...
In the following PHP program factorial of number 5 is calculated. This is a simple program using for loop. This for loop is iterated on the sequence of numbers starting from the number till 1 is reached. Code: <?php //example to calculate factorial of a number using simple for loop ...
Note: To test the program for a different number, change the value of num. Here, the number whose factorial is to be found is stored in num, and we check if the number is negative, zero or positive using if...elif...else statement. If the number is positive, we use for loop and...
returnnum*factorial(num-1);}}intmain(){intnum;// Declare variable to store the input numbercin>>num;// Take input from the user// Displaying the factorial of the input number using the factorial functioncout<<factorial(num)<<endl;return0;// Indicating successful completion of the program}...
Now let's see how we can calculate factorial using the while loop. Here's our modified method: public static int getFactorialWhileLoop(int n){ int result = 1; while (n > 1) { result = result * n; n -= 1; } return result; } This is pretty similar to the for loop. Except ...
