高精度乘法问题,WA了两次是因为没有考虑结果为0的情况. Product The Problem The problem is to multiply two integers X, Y. (0<=X,Y<10250) The Input The input will consist of a set of pairs of lines. Each line in pair contains one multiplyer. The Output For each input pair of…
尝试一下java 的大数类 import java.util.*; import java.io.*; import java.math.BigInteger; public class Main { public static void main(String[] args) { Scanner in = new Scanner(System.in); while(in.hasNextBigInteger()) { BigInteger a = in.nextBigInteger(), b =…

虽然是错的代码,但是还是想贴出来,最开始WA发现是没有考虑到乘积为0的情况,后来把a*0,0*a,a*0---0(若干个0),0--0(若干个0)*a都考虑进去了:可是还是WA,实在不懂先留在这儿. Product The Problem The problem is to multiply two integers X, Y. (0<=X,Y<10250) The Input The input will consist of a set of pairs of lines. Each…
