Solution: Regions Cut by Slashes

Explore how to apply the Union Find algorithm to solve the problem of counting regions cut by slashes in an n x n grid. Understand how to divide each grid square into four parts and merge these parts based on the slash types to find connected components representing distinct regions. This lesson guides you through the solution approach, including its time and space complexities.

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 $\leq$
