Hackerrank Solution Lister Problem

The script reads from a file named 'python_info.txt', which contains the names of problems and their respective subdomains. It then generates a list of these problems and writes them into an HTML file named 'solution_list.html'. The script also handles the formatting of the problem names and subdomain names to ensure they are valid for use in file paths.

Here is the Hackerrank Solution Lister Problem HackerRank solution using CodeRankGPT:

The script uses the built-in Python libraries 'os', 're', and 'sys'. It reads from an input file line by line, and for each line, it checks if it is a problem name or a subdomain name. If it is a problem name, it is added to the problem list. If it is a subdomain name, it is stored as the current subdomain. When both a problem and a subdomain have been found, the script generates a valid folder name from the subdomain name, finds all the titles in the problem list, and writes them into the output HTML file with the appropriate file path. The script continues this process until it has processed all lines in the input file.


import os
import re
import sys

info_file_name = "python_info.txt"

def get_valid_name(given_name):
    return re.sub(r"[^\w]", "", given_name)

problem_list = ""
subdomain_name = ""
extension = ".py"

info_file = open(info_file_name, "r")
info_file_lines = info_file.readlines()
info_file.close()
output_file_name = "solution_list.html"
f = open(output_file_name, "w")
f.write("\n")
for line in info_file_lines:
    line = line.strip()
    if line == "":
        continue
    elif line[0] == "[":
        problem_list = line
    else:
        subdomain_name = line
    if subdomain_name != "" and problem_list != "":
        folder_name = get_valid_name(subdomain_name)
        title_ar = re.findall(r'("[^"]*")', problem_list)
        title_ar_len = len(title_ar)
        f.write("- " + subdomain_name + "\n")
        for title in title_ar:
            filename = get_valid_name(title[1:-1])
            filepath = folder_name + "/" + filename + extension
            f.write("   - [" + title[1:-1] + "](" + filepath + ")\n")
        subdomain_name = ""
        problem_list = ""
f.close()
print("List generated successfully. Open " + output_file_name + " to view.")
