Explanation:

Q > How to calculate?

For example :

Consider :

2! = 2 x 1 = 2

The possibility of 2! is two ways like {2,1}, { 1,2 }.

Same as like :

4! = 4 x 3 x 2 x 1 = 24.

24 = the arrangement of 4! is {1,2,3,4}, {2,1,3,4}, {2,3,1,4}, {2,3,4,1}, {1,3,2,4}, etc.

Same as like 5! , 10! , N!.

Answer 2

Answer:

Consider :

2! = 2 x 1 = 2

The possibility of 2! is two ways like {2,1}, { 1,2 }.

Same as like :

4! = 4 x 3 x 2 x 1 = 24.

24 = the arrangement of 4! is {1,2,3,4}, {2,1,3,4}, {2,3,1,4}, {2,3,4,1}, {1,3,2,4}, etc.

Same as like 5! , 10! , N!.

public static void main(String arg[])

{

int n=5,fact=1;

for(int i=1;i<=n;i++)

{

fact=fact*i;

}

System.out.println("factoral="+fact);

}
