40选择题，2道编程题。

1. 第一道编程很简单，根据研究生的四门课入学成绩判断，Fail或Gongfei，Zifei。

import java.util.Scanner;/** * Created by aifei on 15/9/15. */public class Main {    public static void main(String[] args) {        Scanner sc = new Scanner(System.in);        int n = sc.nextInt();        while(n-->0){           int []score = new int[4];            for(int i = 0;i<4;i++){                score[i] = sc.nextInt();            }            int sum = score[0] + score[1] + score[2] + score[3];            if(!isFail(score,sum)){                System.out.println("Fail");            }else{                if(sum>=310 && sum<=349){                    System.out.println("Zifei");                }else{                    System.out.println("Gongfei");                }            }        }     }    private static boolean isFail(int[] score,int sum) {        if(score[0]>=60 && score[1]>=60 && score[2]>=90 && score[3]>=90 && sum>=310){            return true;        }else {            return false;        }    }}

2. 素因子分解，并以可视化数字输出素因子。

import java.util.ArrayList;import java.util.Scanner;/** * Created by  on 15/9/15. */public class Main {    public static void main(String[] args) {        Scanner sc = new Scanner(System.in);        while(sc.hasNext()){            int n = sc.nextInt();            ArrayList<Integer> list = new ArrayList<Integer>();            int key = 1;            while(n > 1){                for(int i=2; i<=n;i++){                    if(n%i==0){                        key = i;                        list.add(key);                        break;                    }                }                n = n/key;             }            for(int i=0; i<list.size();i++){                if(i!=list.size()-1){                    visualOutPut(list.get(i));                    System.out.print("*");                }else{                    visualOutPut(list.get(i));                }            }         }    }    private static void visualOutPut(int num) {        String str = String.valueOf(num);        for(int i=0; i<str.length();i++){            char ch = str.charAt(i);            visualDigit(ch);        }    }    private static void visualDigit(char ch) {        switch (ch){            case '0':                System.out.println(" "+'-');                System.out.print("|");                System.out.println(" "+"|");                System.out.println(" "+'-');                System.out.print("|");                System.out.println(" "+"|");                System.out.print(" "+'-');                break;            case '1':                System.out.println("|");                System.out.println('|');                break;            case '2':                  System.out.println(" "+'-');                  System.out.println("  "+"|");                  System.out.println(" "+'-');                  System.out.println('|');                  System.out.println(" "+'-');                  break;            case '5':                System.out.println(" "+'-');                System.out.println("|");                System.out.println(" "+'-');                System.out.println("  "+'|');                System.out.print(" "+'-');                break;        }    }}
