Eclipse 无法找到 该 断点,原因是编译时,字节码改变了,导致eclipse无法读取对应的行了 1.ANT编译的class Eclipse不认,因为eclipse也会编译class.怎么让它们统一呢,就是在build.xml里的javac标签里加上一句debug="true",一切就OK了. 如:<javac ... debug="true"> 链接:http://blog.csdn.net/liu251/article/details/36391…

Given n points on a 2D plane, find if there is such a line parallel to y-axis that reflect the given set of points. Example 1: Given points = [[1,1],[-1,1]], return true. Example 2: Given points = [[1,1],[-1,-1]], return false. Follow up: Could you d…

How would you print just the 10th line of a file? For example, assume that file.txt has the following content: Line 1 Line 2 Line 3 Line 4 Line 5 Line 6 Line 7 Line 8 Line 9 Line 10 Your script should output the tenth line, which is: Line 10 [show hi…

Given n points on a 2D plane, find the maximum number of points that lie on the same straight line. 这道题给了我们一堆二维点,然后让我们求最大的共线点的个数,根据初中数学我们知道,两点确定一条直线,而且可以写成y = ax + b的形式,所有共线的点都满足这个公式.所以这些给定点两两之间都可以算一个斜率,每个斜率代表一条直线,对每一条直线,带入所有的点看是否共线并计算个数,这是整体的思路.但是还有…

Linux和Windows文本文件的行结束标志不同.在Linux中,文本文件用"/n"表示回车换行,而Windows用"/r/n"表示回车换行.有时候在Windows编写shell脚本时需要注意这个,否则shell脚本会报"No such file or directory"或"command not found line x"之类的错误,如果不知晓前因后果,肯定会被这个折腾得相当郁闷.如下所示test.sh [root@DB…

题目链接 Given n points on a 2D plane, find the maximum number of points that lie on the same straight line. 分析:首先要注意的是,输入数组中可能有重复的点.由于两点确定一条直线,一个很直观的解法是计算每两个点形成的直线,然后把相同的直线合并,最后包含点最多的直线上点的个数就是本题的解.我们知道表示一条直线可以用斜率和y截距两个浮点数(垂直于x轴的直线斜率为无穷大,截距用x截距),同时还需要保存每…

Max Points on a Line 题目描述: Given n points on a 2D plane, find the maximum number of points that lie on the same straight line. 解题思路: 1.首先由这么一个O(n^3)的方法,也就是算出每条线的方程(n^2),然后判断有多少点在每条线上(N).这个方法肯定是可行的,只是复杂度太高2.然后想到一个O(N)的,对每一个点,分别计算这个点和其他所有点构成的斜率,具有相同斜率最…
