原题链接:小O的数字
解题思路:
这题考察 switch, 按数字和行号区分图案即可
注意事项:
参考代码:
import java.util.Scanner; public class C1787 { public static void main(String[] args) { Scanner sc = new Scanner(System.in); while (sc.hasNext()) { int n = sc.nextInt(); String num = String.valueOf(n); for(int i = 1; i <= 5; i++){ for(int j = 0; j < num.length()-1; j++){ System.out.printf("%s ", F(Integer.valueOf(""+num.charAt(j)), i)); } System.out.printf("%s\n", F(Integer.valueOf(""+num.charAt(num.length()-1)), i)); } } sc.close(); } private static String F(int num, int line){ switch(num){ case 0: if(line == 1 || line == 5) return "***"; else return "* *"; case 1: return " *"; case 2: if(line % 2 == 1) return "***"; else if(line == 2) return " *"; else return "* "; case 3: if(line % 2 == 1) return "***"; else return " *"; case 4: if(line < 3) return "* *"; else if(line == 3) return "***"; else return " *"; case 5: if(line % 2 == 1) return "***"; else if(line == 2) return "* "; else return " *"; case 6: if(line % 2 == 1) return "***"; else if(line == 2) return "* "; else return "* *"; case 7: if(line == 1) return "***"; else return " *"; case 8: if(line % 2 == 1) return "***"; else return "* *"; case 9: if(line % 2 == 1) return "***"; else if(line == 2) return "* *"; else return " *"; } return ""; } }
