Given n points, we need to check if these n points are parallel to X axis or Y axis or to No axis.
Examples:
Input : x[] = {0, 0, 0, 0, 0|
y[] = {9, 2, 1, 3, 4}
Output : Parallel to Y Axis
Input : x[] = {1, 2, 3|
y[] = {9, 2, 1}
Output : Not Parallel to X or Y Axis
Approach
To find the points parallel to X or Y axis just check if the points are same for any axis or not. If all the points on X axis are same then the line is parallel to Y axis. If all the points on Y axis are same so the line is parallel to X axis. If none of the cases is true, then it is not parallel to any axis.
Input the value N. And then Input the value of points in a

Output:
