HDOJ-ACM1013(JAVA)
这道题也很简单~主要是将输入转为字符串(存储大数,操作字符数组)
题意:
24 : 2 + 4 = 6 输出6
39 : 3 + 9 = 12 , 1 + 2 = 3 输出3
999: 9 + 9 + 9 = 27 , 2 + 7 = 9 输出9
Java代码如下:
import java.util.*; import java.io.*; public class Main{ public static void main(String[] arg){ Scanner scan = new Scanner(new BufferedInputStream(System.in)); String s; while(true){ s=scan.next(); char[] cs = s.toCharArray(); if(cs[0] == '0'){ break; } if(cs.length==1){ System.out.println(s); continue; } System.out.println(getSum(cs)); } scan.close(); } static int getSum(char[] cs){ int sum = 0; while(cs.length!=1){ sum = 0; for(int i = 0 ; i != cs.length ; i ++ ){ sum = cs[i]-'0' + sum; } cs = String.valueOf(sum).toCharArray(); } return sum; } }
