## 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)
