用java测试都对,为什么wa啊import java.util.*; import java.math.BigInteger; public class Main{ static int p(int w,int e) { int s=1,q; for(q=0;q<e;q++) s*=w; return s; } public static void main(String[] args) { Scanner cin=new Scanner(System.in); String n; while(cin.hasNext()) { n=cin.nextLine(); int l=n.length(); if(l==1) {if(Integer.valueOf(n)==0)System.exit(0);} else { BigInteger sum=new BigInteger("0"); for(int j=0;j<l;j++) { int r=(int)n.charAt(j)-'0'; int x=r*(p(2,l-j)-1); sum=sum.add(new BigInteger(Integer.toString(x))); } System.out.println(sum);} } } } Followed by: Post your reply here: |
