## Description
- Add headers to all the CSV files

## Script used
```py
import csv
import os

# Set the path of the folder containing the CSV files
folder_path = "./LeetCode-Questions-CompanyWise"
headers = [
    "ID",
    "Title",
    "Acceptance",
    "Difficulty",
    "Frequency",
    "Leetcode Question Link",
]

# Loop through all the CSV files in the folder
for file_name in os.listdir(folder_path):
    if file_name.endswith(".csv"):
        # Read the CSV file into a list of rows
        file_path = os.path.join(folder_path, file_name)
        with open(file_path, "r") as f:
            reader = csv.reader(f)
            rows = list(reader)

        has_headers = False
        if len(rows) > 0 and rows[0] == headers:
            has_headers = True

        if not has_headers:
            rows.insert(0, headers)

            # Write the list of rows back to the CSV file
            with open(file_path, "w", newline="") as f:
                writer = csv.writer(f)
                writer.writerows(rows)
