Find Duplicate Files by Content from Directory List

anthropic Coding Problem Given a directory structure, find all files with duplicate content. The contents of each file can be simplified using a hash function to a string for comparison. Requirements Input is a list of strings representing file paths, each containing file contents. Output the list of files grouped by their content. Example Input: [ "root/a 1.txt(abcd) 2.txt(efgh)", "root/c 3.txt(abcd)", "root/c/d 4.txt(efgh)", "root 4.txt(1234)" ] Output: [ ["root/a/1.txt", "root/c/3.txt"], ["root/a/2.txt","root/c/d/4.txt"] ] Constraints Each input string's length is less than 300. The number of files is less than 10^4. Example Input ["root/a 1.txt(abcd) 2.txt(efgh)"]
