<content type="text"><![CDATA[题目In MATLAB, there is a very useful function called ‘reshape’, which can reshape a matrix into a new one with different size but keep its original data. You’re given a matrix represented by a two-dimensional array, and two positive integers r and c representing the row number and column number of the wanted reshaped matrix, respectively. The reshaped matrix need to be filled with all the elements of the original matrix in the same row-traversing order as they were. If the ‘reshape’ operation with given parameters is possible and legal, output the new reshaped matrix; Otherwise, output the original matrix. Example 1:Input: nums = [[1,2], [3,4]]r = 1, c = 4Output: [[1,2,3,4]]Explanation:The row-traversing of nums is [1,2,3,4]. The new reshaped matrix is a 1 * 4 matrix, fill it row by row by using the previous list. Example 2:Input: nums = [[1,2], [3,4]]r = 2, c = 4Output: [[1,2], [3,4]]Explanation:There is no way to reshape a 2 2 matrix to a 2 4 matrix. So output the original matrix. Note:The height and width of the given matrix is in range [1, 100].The given r and c are all positive.

<content type="text"><![CDATA[iOS开发中，内存问题一直是个长久不变的问题。这不，项目间歇间，用xcode自带的Leak跑了一下程序，发现了几个内存泄漏的地方，都是平时自己没有注意到的，并做出相应改正。在这里记录下。 1.运行程序让程序先跑起来 2.进入Leak工具 如上图，选中show the debug（箭头指的），然后点击Memory 然后点击profile in instruments,通过Leak重新运行程序(弹出框中选择Restart 3.操作Leak工具 如上图，此时程序在跑起来了，Leak Checks右边显示绿色的钩，表示当前没有内存泄漏，这时候我们就可以操作我的app了，跑起来吧，直到发现有红色的X，表示在这里有内存泄漏，如下图 点击红色X，选择Call Tree，如下图 这时候下面的列表会出来很多方法，但都是系统的，表示看不懂有木有啊。。。这时候点击右边中间的选项，然后勾选Call Tree下的Separate by Thread 和 Hide System Libraries，如下图 然后再看左右，下面列表的方法就会变成了我们自己写的方法了，如下图 在这里，有的人肯定会有疑问，为啥他的列表里的方法都是一些进制类的看不懂的，或者就是空白，这是因为Xcode编译项目后，我们会看到一个同名的 dSYM 文件，dSYM 是保存 16 进制函数地址映射信息的中转文件，我们调试的 symbols 都会包含在这个文件中，并且每次编译项目的时候都会生成一个新的 dSYM 文件。显示进制是因为我们的工程build settings 的问题，没有生成dSYM 文件，也就无法解析debug symbols。做法如下图 在Build Options将Debug information Format选择dsYM，这里默认的可能是release下选择的，将debug下也选择就可以了。然后重新从编译，重新运行，从第一步重新走一遍即可出来最后双击列表中暴露出来的方法，会直接显示代码，神不神奇~ 利用这个调试方法，里里外外将我们程序跑一跑，将内存泄漏的地方都改过来，这样程序闪退的机率将会大大减小。 关于product->analyze分析内存泄漏的问题优点：分析速度快，并且可以对所有的代码进行内存分析缺点：分析结果不一定准确（没有运行程序，根据代码的上下文语法结构）所以最好还是用Leak工具进行动态运行检查。 路漫漫其修远兮，吾将上下而求索，与君互勉。]]></content>
