解析二維陣列

Description

讀入一個字串,該字串表示一個整型二維陣列d,陣列中的元素通過解析字串引數獲得。例如,字串引數:“1,2;3,4,5;6,7,8”,對應的陣列為:
d[0,0] = 1 d[0,1] = 2  
d[1,0] = 3 d[1,1] = 4 d[1,2] = 5
d[2,0] = 6 d[2,1] = 7 d[2,2] = 8
列印這個陣列各元素的內容

Input

字串

Output

二維陣列各元素

Sample Input

1,2;3,4,5;6,7,8

Sample Output

d[0,0] = 1 d[0,1] = 2
d[1,0] = 3 d[1,1] = 4 d[1,2] = 5
d[2,0] = 6 d[2,1] = 7 d[2,2] = 8

        String s = scan.nextLine();

        int rank = 0;

        for(int i=0;i<s.length();i++)

        {

            char o = s.charAt(i);

            if(o == ';')

            {

                System.out.println();

                row++;

                rank = 0;

            }

            else if(i>=1 && o>='0' && o<='9' && s.charAt(i-1)>='0' && s.charAt(i-1)<='9')

                System.out.print(o);

            else

                System.out.print("d[" + row + "," + rank +"] = "+o);
