G面经Prepare: Print Zigzag Matrix

For instance, give row = 4, col = 5, print matrix in zigzag order like:

[1, 8, 9, 16, 17]
[2, 7, 10, 15, 18]
[3, 6, 11, 14, 19]
[4, 5, 12, 13, 20]

 import java.util.Arrays;

 public class PrintMatrix {

     static void print(int rows, int cols) {
         int limit = rows * cols;
         int T = rows * 2; // cycle
         for (int i=1; i<=rows; i++) {
             int[] curRow = new int[cols];
             int k = 0;
             int index = 0;
             while (k * T + i <= limit || k * T + T - i + 1 <= limit) {
                 if (k * T + i <= limit) curRow[index++] = k * T + i;
                 if (k * T + T - i + 1 <= limit) curRow[index++] = k * T + T - i + 1;
                 k++;
             }
             System.out.println(Arrays.toString(curRow));
         }
