［抄题］: Given two 1d vectors, implement an iterator to return their elements alternately. Example: Input: v1 = [1,2] v2 = [3,4,5,6] Output: [1,3,2,4,5,6] Explanation: By calling next repeatedly until hasNext returns false,   the order of elements retur…

问题:给定 n 行和 m 列的二维数组矩阵.如图所示,以 ZIG-ZAG 方式打印此矩阵. 从对称的角度来看,通过反复施加滑行反射可以从简单的图案如线段产生规则的之字形. 主要思想:算法从(0, 0)位置开始水平向右遍历,当到达(0, 1)时沿着反对角线方向左下遍历(利用一个变量控制左下右上方向),内层循环一直遍历到碰到边缘时row++,方向改为右上,沿着反对角线碰到矩阵上边缘时col++,方向变为左下遍历,知道上半部分(包括反对角线遍历完):遍历完半个矩阵(可能是子方矩阵)后,根据当前 row…
