1、给定一个字符串,统计最长的连续元音字符串。长度小于655535，难度1星
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Scanner;
public class Main {
public static void main(String[] args) throws IOException {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
String s = null;
while ((s=reader.readLine())!=null){
int count=0;
int max = 0;
if (null==s){
continue;
}
char[] chars = s.toLowerCase().toCharArray();
for (int i=0;i=max){
max=count;
}
count=0;
}
}
//全部都是元音的情况
if (count>=max){
max=count;
}
System.out.println(max);
}
}
}
2、打车打表器没有数字4，遇到数字4跳过。给定一个打表器上的数字推算实际金额。打
表器遇到4,14,24,34,40,41,42.。。。49都不在记录内。例如打表显示5实际金额是4，打表
显示25实际是22。难度1星import java.io.BufferedReader;
