Graham Scan Algorithm Doubt

In the video when the polar angle is == 180 the point is removed from the stack, it should be on a side of the convex hull, right? Then why it is not taken ??

Hey @anirbandas0206
Can you please mention the point in the video where this happened ?

Yes sure , 9.44 look from this point.

@anirbandas0206
In case 3 points are collinear then you can simply connect the first and last point since the middle one just lies on this line and does not really contribute any info
Thats why we didnt keep that point

If your doubt is resolved please close it
