定义一个Point类，其属性包括点的坐标，提供计算两点之间距离的方法

说明：   有一个长度为整数L(1<=L<=10000)的马路，可以想象成数轴上长度为L的一个线段，起点是坐标原点，在每个整数坐标点有一棵树，即在0,1,2，...，L共L+1个位置上有L+1棵树。 现在要移走一些树，移走的树的区间用一对数字表示，如 100 200表示移走从100到200之间（包括端点）所有的树。 可能有M(1<=M<=100)个区间，区间之间可能有重叠。现在要求移走所有区间的树之后剩下的树的个数。 输入： 两个整数L(1<=L<=10000)和M(1<=M<=100)。 接下来有M组整数，每组有一对数字。 输出： 可能有多组输入数据，对于每组输入数据，输出一个数，表示移走所有区间的树之后剩下的树的个数。(Has a length of integer L (1 &lt = L &lt = 10000) of the road, one can imagine a number line segment of length L, the starting point is the coordinate origin, each integer coordinate points in a tree, i.e. 0,1 , 2, ..., L total has L+1 L+1 positions on the tree. Now to remove some trees, tree removed by a range of digitally represented, such as 100 200 represents removed (inclusive) between 100 and 200 all the trees. There may be M (1 &lt = M &lt = 100) intervals, there may be overlap between the intervals. Now, after the number of trees require the removal of all remaining sections of the tree. Input: two integer L (1 &lt = L &lt = 10000) and M (1 &lt = M &lt = 100). Then there is an integer M groups, each with a pair of numbers. Output: there may be multiple sets of input data, for each set of input data, the output of a number indicating the number of the removal of all remaining sections of the tree after tree.)

实现了素数的拆分和。只是很简单，没写麻烦的，复杂的可找我，呵呵(Realized primes splitting and. Very simply, I did not write cumbersome and complicated to find me, Oh)

GPS定位数据解析，GPS设备通过对接收到的导航电文进行分析处理，计算出设备所在的经纬度、海拔、航速、航向等空间信息，并按照规定的NMEA-0183协议将空间信息以及卫星信息进行组织，按照一定的波特率通过串口通讯（按位发送）提供给GPS设备使用者或者在GPS设备上进行显示(GPS positioning data analysis, GPS device by the received navigation message analysis and processing equipment where the calculated latitude and longitude, altitude, speed, heading and other spatial information and spatial information and satellite information is organized in accordance with the provisions of the NMEA-0183 protocol , according to the baud rate of serial communication (bits sent) to the users of GPS devices or GPS devices on display)
