import java.util.Scanner;
public class Main{
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        int a = sc.nextInt();
        int count = 1;
        for(int i = 1;i<=a;i++){
            count *=i;
            System.out.println(i+" = "+count);
        }
    }
}

so here it forms a for loop and i starts from 1 to input value a has firstly count = 1, and count value is 1 and for 1st loop run value of count = 1*1 = 1 As in the statement count*=i it says(count = count *i) as so for 2nd loop run i value is 2 so count=1*2=2 and so on........ i hope you get it if else feel free to ask me i will assist you!! :)
