Grokking the Coding Interview Patterns in Python

Solution: Convex Polygon

Understand how to determine if a polygon formed by points is convex by using the cross product of vectors between consecutive points. Learn to check the turn direction consistently to verify convexity, enhancing your approach to solving geometric coding challenges.

We'll cover the following...

Statement

You are given an array of points on the XY plane, where each point is represented as points[i] = [xi, yi][x_i, \space y_i] ...
