由王兴刚、白翔等人发表于2012CVPR上的文章，Fan Shape Model for Object Detection， 构建了全新的模型用于物体检测，师兄的这个组工作一直做得不错，赞一个！(The article from PROCEEDINGS, White Xiang et al published in 2012CVPR on, Fan Shape Model for Object Detection, build a new model for object detection, this group of brothers has done a good job, like this one!)

给你一个非常大的整数x，(-10^400 <=x<= 10^400)，请统计x的每一位，分别输出9,1,2出现的次数. Input 一个大整数 Output 一共三行，第一行是9出现的次数，第二行是1出现的次数，第三行是2出现的次数。 Sample Input 912912912910915902 Sample Output 6 5 4(Statistical figures)

利用matlab的数据处理和数据模拟功能，模拟光的反射，光的折射，以及光的透射，并且生成模拟曲线，可以直观的观察到光功率和相关参数的变化关系(Use of matlab data processing and data simulation function, simulation light reflection, the refraction of light, and light transmission, and generate simulation curves can be intuitive observed light power and related parameters change relations)
