ZigBee无线通信，定位算法研究

因为“ZigBee”这个词由“Zig”和“Bee”两部分组成，“Zig”取自英文单词“zigzag”，意思是走“之”字形，“bee”英文是蜜蜂的意思，所以“ZigBee”就是跳着“之”字形舞的蜜蜂。

ZigZag Conversion 锯齿形转换字符串

思路：根据锯齿形状，可以得到结论第i行的字符下标之间的距离是(nRows-1-i)*2和2*i，如下图所示：0      61   5  72 4   83      9根据这个规律，遍历每一行的元素，得到转换后的字符串。注意两点：1.当s.length<=nRows||nRows==1时，无需转换，直接返回，否则会超时。2.在遍历每一行时，每一行的while条件是下标值

把一个字符串按照“之”字形复制在矩阵中，再把结果逐行逐列输出。原理和配图在这里。看上去题目很简单，实际上有些下标相关的东西我想了很久也debug了很久才弄清楚，更吐血的事情是，提交的时候说超时了。囧，说明办法太笨。之前采用的办法是new用一个二维数组作为中间变量，存入“之”字形字符串，再扫描一遍二维数组，把最终结果输出。这样老老实实地转换，时间当然消耗得久了。换了个办法，找到原字符串的下标和转换后
