Solution: Find Duplicate File in System
Explore how to find duplicate files within directory paths by parsing directory and file information, then using hash maps to group files by identical content. Learn the step-by-step process to split and store file data and how to return groups of duplicates, along with understanding the associated time and space complexity.
We'll cover the following...
Statement
Given a list of directory information named paths, where each directory contains file paths and their respective contents, identify all the duplicate files in the system based on their contents. Each duplicate group should contain at least two files with identical content, and the output should list these groups with the full paths of the duplicate files. Each entry in the input list is formatted as follows:
"root_directory/dir_1/dir_2/…/dir_m file_1.txt(file_1_content) file_2.txt(file_2_content) … file_n.txt(file_n_content)"
This indicates there are n files (file_1.txt, file_2.txt, …, file_n.txt) with respective contents (file_1_content, file_2_content, …, file_n_content) in the directory "root_directory/dir_1/dir_2/…/dir_m". The output should be a list of groups containing the paths of files sharing the same content. Each file path should follow the format given below:
"directory_path/file_name.txt".
The order of the groups or the paths within them does not matter.
