用java写的大数基本操作,java要求的格式比较严谨。
1 import java.util.*; 2 import java.math.*; 3 public class Main { 4 public static void main(String args[]) { 5 Scanner cin = new Scanner(System.in); 6 7 BigInteger a,b,ans; 8 String c; 9 b = BigInteger.valueOf(1);10 a = BigInteger.valueOf(1);11 // BigInteger zero=new BigInteger("0");12 13 while(cin.hasNext())14 {15 a=cin.nextBigInteger();16 c=cin.next();17 b=cin.nextBigInteger();18 if(c.equals("/"))19 ans = a.divide(b);20 else21 ans=a.mod(b);22 System.out.println(ans);23 }24 return ;25 }26 27 }
