Solution: Regions Cut by Slashes

Understand how to use the union find pattern to solve the problem of counting regions cut by slashes in a grid. Explore dividing grid squares into parts, merging regions based on slashes, and connecting adjacent boxes to find distinct connected components. This lesson improves your grasp of union find through practical application and complexity analysis.

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 $\leq$
