编程检查点是否平行于X轴或Y轴-yiteyi-C++库

给定n个点，我们需要检查这n个点是否平行于X轴或Y轴，或者不平行于任何轴。

null

例如：

Input : x[] = {0, 0, 0, 0, 0|        y[] = {9, 2, 1, 3, 4}Output : Parallel to Y AxisInput : x[] = {1, 2, 3|        y[] = {9, 2, 1}Output : Not Parallel to X or Y Axis

方法

要找到与X或Y轴平行的点，只需检查任何轴的点是否相同。如果X轴上的所有点都相同，则该线平行于Y轴。如果Y轴上的所有点都相同，那么这条线平行于X轴。如果这些情况都不成立，那么它就不平行于任何轴。输入值N，然后输入a中的点的值
