Solution: Regions Cut by Slashes

Explore how to apply the union find pattern to solve the problem of counting distinct regions created by slashes in a grid. Understand how each 1x1 box is divided into four parts, how to merge connected parts based on slash characters, and how to traverse the grid to identify connected components representing regions. This lesson enhances your ability to solve graph and connectivity problems efficiently.

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 $\leq$
