Understanding the Alternating Groups I I Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
There is a circle of red and blue tiles. You are given an array of integers colors and an integer k. The color of tile i is represented by colors[i]: colors[i] == 0 means that tile i is red. colors[i] == 1 means that tile i is blue. An alternating group is every k contiguous tiles in the circle with alternating colors (each tile in the group except the first and last one has a different color from its left and right tiles). Return the number of alternating groups. Note that since colors represents a circle, the first and the last tiles are considered to be next to each other.
