Problem: Find Duplicate File in System

Statement

You are given a list paths, where each element is a string representing directory information. Each string contains a directory path followed by one or more files along with their contents in the following format:

"root/d1/d2/.../dm f1.txt(f1_content) f2.txt(f2_content) ... fn.txt(fn_content)"

This indicates that there are n files (f1.txt, f2.txt, …, fn.txt) with contents (f1_content, f2_content, …, fn_content) respectively, all located in the directory "root/d1/d2/.../dm". Here, n $\geq 1$ and m $\geq 0$. When m $= 0$, the directory is simply the root directory. A single blank space separates the directory path from each file entry.

Your task is to identify all groups of duplicate files in the file system. A group of duplicate files consists of at least $2$ files that share the same content. For each such group, return the full file paths of all files with that identical content. A file path follows the format:

"directory_path/file_name.txt"

Return a list of all such groups. The answer may be returned in any order.

Note: You may assume that no files or directories share the same name within the same directory, and that each given directory info string represents a unique directory.

Constraints:

• $1$ ...
