WhereIsHeroFrom: Zty, what are you doing ? Zty: I want to calculate N!.. WhereIsHeroFrom: So easy! How big N is ? Zty: 1 <=N <=1000000000000000000000000000000000000000000000… WhereIsHeroFrom: Oh! You must be crazy! Are you Fa Shao? Zty: No. I haven’s finished my saying. I just said I want to calculate N! mod 2009
Hint : 0! = 1, N! = N*(N-1)! Input Each line will contain one integer N(0 <= N<=10^9). Process to end of file. Output For each case, output N! mod 2009 Sample Input 4 5 Sample Output 24 120
