蔚来8.28笔试java
java后端编程前两题AC，第一题leetcode原题我做过
第三题二段数有大佬帮我解释一下嘛 在本地跑可以按照题目意思跑通，为啥 放到牛客就超时了？？
是我的输出格式问题吗
import javax.sound.midi.Soundbank;
import java.util.*;
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
ArrayList<String> list = new ArrayList<>();
while (sc.hasNext()){
String cur = sc.next();
if(cur=="0") {
break;
}
Long mul = 1L;
Long num = Long.parseLong(cur);
Long res = 1L;
while(true){
res = num*mul;
String res2 = String.valueOf(res);
int count =0;
int i =0;
boolean b =false;
while(i<res2.length()-1){
if(count>1) break;
if(res2.charAt(i)!=res2.charAt(i+1)){
count++;
}
if(i==res2.length()-2 && count==1 ) b = true;
i++;
}
if(b){
list.add(cur+":"+res);
System.out.println(cur+":"+res);
break;
}
mul++;
}
}
sc.close();
for (int i = 0; i < list.size(); i++) {
System.out.println(list.get(i));
}
}
} 本地结果为：
