小米加携程笔试

第一题是匹配单词，有数字，符号，大写字母，小写字母四种类型，还有特定长度为8到120，四个符号都有且长度满足则输出0，若长度不满足则输出1，若没完全包含四个符号则输出2；

过了83%还有一个用例不知道怎么过，

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        Scanner in=new Scanner(System.in);
        while(in.hasNext()){
            String s=in.next();
            char[] ch=s.toCharArray();
            int length=ch.length;
            if(length<8||length>120){
                System.out.println(1);
                continue;
            }
            int num=0;
            int bigwrite=0;
            int smallwrite=0;
            int zifu=0;
            for(int i=0;i<ch.length;i++){
                if(ch[i]>='0'||ch[i]<='9'){
                    num++;
                }
                if(ch[i]>='a'||ch[i]<='z'){
                    smallwrite++;
                }
                if (ch[i]>='A'||ch[i]<='Z'){
                    bigwrite++;
                }
                if(ch[i]=='!'&&ch[i]=='#'&&ch[i]=='$'){
                zifu++;
                }
            }
            if(num>0&&bigwrite>0&&smallwrite>0&&zifu>0){
                System.out.println(0);
            }
            else{
                System.out.println(2);
            }
        }
    }
}

好了，直接看第二题没有网格看了十分钟，没时间了，直接骗了50%，输出个true；转去携程辽

携程选择比小米难一点，编程也难

1.过了77%，逗号不知如何去掉，搞了半天

import java.util.HashMap;
import java.util.Scanner;
import java.util.Map;

public class Main {

    public static void main(String[] args) {
        Scanner in=new Scanner(System.in);
        String target=in.nextLine();
        String ischeck=in.nextLine();
        String instead=in.nextLine();
       
            StringBuilder sb = new StringBuilder();
            String[] strings = ischeck.split(" ");

            Map<Character, Integer> map1 = new HashMap<Character, Integer>();
            for (int k = 0; k < target.length(); k++) {
                if (!map1.containsKey(target.charAt(k))) {
                    map1.put(target.charAt(k), 1);
                } else {
                    map1.put(target.charAt(k), map1.get(target.charAt(k)) + 1);
                }
            }
            for (int i = 0; i < strings.length; i++) {
                char[] ch = strings[i].toCharArray();
                Map<Character, Integer> map = new HashMap<Character, Integer>();
                int j;
                for ( j = 0; j < ch.length; j++) {
                    
                    if (!map.containsKey(ch[j])) {
                        map.put(ch[j], 1);
                    } else {
                        map.put(ch[j], map.get(ch[j]) + 1);
                    }
                }
              

                if (map.equals(map1)) {
                    strings[i] = instead;
                }
                sb.append(strings[i] + " ");
            }
            System.out.print(sb.toString());
        }
    }
}

2.第二题看了一下，直接骗了13%

3.第三题亦是如此，也骗了13%

流下菜鸡的泪水，
