最近在研究数据结构和简单算法，为了准备某某东西嘛，就不说出来了，因为是新手，而且和也可能和我的学习方法以及悟性有关
感觉一直很颓废，写起来没有那么生动，思考的时候容易遇到瓶颈，而且我感觉算法和数据结构这种东西不是突击就可以出来的，
不过最近我又开始加班了，以后打算长期写下去，希望这个家可以长久一点，一开始本来是在本地计算机的虚拟机里搭建WP的，只是想有个稳定点的家而已。
关于链表的结构还是比较清晰的，就是类似数组类型的简单数据结构，但是在运算以及存储操作等方法上要优于数组，特别是在使用
C/CPP这样的比较接近底层的语言中，因为语言本身没有比较好的高级数据结构，不过就链表的实现来说还是很方便的，在我书写的过程中，主要遇到的困难是，链表指针的传递问题，有好几次我的指针都不知道指向了什么地方，经过相当长时间的刻苦调试终于有了进展，不过参看别人的链表结构我感觉自己的结构还是相当幼稚的，这是我今天做的总结。
下面上程序，希望自己能快点进步，能成为一名ios开发者，加油！

Some Safety Precautions to take while plying Airsoft 1. Always take care of your airsoft gun. Clean it well with cloth, after each game. Lubricate the internal parts of the gun with SILICONE SPRAY! 2. Know what you want when buying airsoft. Heavier BB's weigh more. Though the weight makes them target more accurately, they are not as far or fast. Lighter BB's like .12 and .20 travel further and faster but are less accurate. .23 though are really hard to find, gives you both fastness and accuracy. Selecting the right BB for the job will give you satisfaction in the game. Do not buy less than a .20 for use in an AE.
