蓝桥杯算法提高VIP-栅格打印问题-题解（Java代码）

解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

Scanner scanner=new Scanner(System.in);

while(scanner.hasNext()) {

int m=scanner.nextInt();

int n=scanner.nextInt();

if(m==0||n==0)

continue;

for(int i=1;i<=2*m+1;i++) {

if(i%2!=0) {

for(int j=1;j<=2*n+1;j++) {

if(j%2!=0)

System.out.print("+");

else

System.out.print("-");

}

}

else {

for(int j=1;j<=2*n+1;j++) {

if(j%2!=0)

System.out.print("|");

else

System.out.print(" ");

}

}

System.out.println();

}

}

}

}
