Solution: Regions Cut by Slashes

Explore how to solve the problem of counting regions separated by slashes in an n by n grid using the Union Find algorithm. Learn to represent each grid cell as four parts, merge regions based on slashes or spaces, and connect adjacent cells. Understand how to efficiently determine the number of distinct regions, analyze time and space complexity, and deepen your grasp of graph connectivity techniques with practical JavaScript solutions.

Statement

An $n \times n$ grid is composed of $n$ , $1 \times 1$ squares, where each $1 \times 1$ square consists of a “/”, “\”, or a blank space. These characters divide the square into adjacent regions.

Given the grid represented as a string array, return the number of regions.

Note:

Backslash characters are escaped, so “\” is represented as “\\”.

A $1 \times 1$ square in the grid will be referred to as a box.

Constraints:

The grid consists of only “/”, “\”, or " " characters.
1 $\leq$ grid.length $\leq$
