Just after this tutorial, I was wondering what would happen if I try to traverse a 2D array, say: int[][] arr = new int[3][2]; // Some codes to assign values to the arr

2. Solution **解析:**Version 1,根据矩阵对角线的规律,对角线的数量为m+n-1,对角线的起点(左下到右上)为第一列加上最后一行的数据,顺序为行数一次加1,列不变,到左下角后,行数不变,列数依次加1,对角线上的数据依次为行减1,列加1。由于是对角线遍历是连续的,因此,行数加列数的和为奇数时,需要反转...

1. In function breadthFirstSearch(), a boolean array is created and visited value of the source is set to true. 2. Then a queue is created and source vertex is added to it. 3. The loop while(!queue.isEmpty()) traverses until the queue is empty. ...
