三道编程，每道100分

1.签到题对应加和输出就完了

AC

import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        long []ans = new long [4];
        //atk atkper def spd
        for(int i = 0;i<6;i++){
            String s = in.next();
            switch (s){
                case "atk":ans[0]+=in.nextInt();break;
                case "atkper":ans[1]+=in.nextInt();break;
                case "def":ans[2]+=in.nextInt();break;
                case "spd":ans[3]+=in.nextInt();break;
            }
            int n = in.nextInt();
            for(int j=0;j<n;j++){
                String st = in.next();
                switch (st){
                    case "atk":ans[0]+=in.nextInt();break;
                    case "atkper":ans[1]+=in.nextInt();break;
                    case "def":ans[2]+=in.nextInt();break;
                    case "spd":ans[3]+=in.nextInt();break;
                }
            }
        }
        System.out.println("atk "+ans[0]);
        System.out.println("atkper "+ans[1]);
        System.out.println("def "+ans[2]);
        System.out.println("spd "+ans[3]);
    }
}

2.n个位置，每个位置可以放1到7的任意数（包含1和7），要求n个数相加为m时，对于每个1到7的每个i，给出i能出现的最多次数。

考虑过dp，没搞出来，痛苦面具

过10%

思路：m/i大于n或刚好等于n的，说明i的出现最多次数就是m/i；否则，emm,不好说

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        while (in.hasNextInt()) {
            int n = in.nextInt();
            int m = in.nextInt();
            int []ans = new int[8];
            for(int i = 7;i>=1;i--){
                if(m/i<n || ( m/i==n && m%i==0))ans[i]=(m/i);
                else{for(int j = 1;j<n;j++){
                        if(i*j+7*(n-j)>=m){
                            ans[i]++;
                        }else break;
                    }
                }

            }
            for(int i = 1;i<=7;i++){
                System.out.println(ans[i]);
            }
        }
    }
}

3.题目没怎么看就跑路了，看到路径就头疼

直输-1骗了5%
