Sure, here's a modified version of the program that parses the CSV file without using a library:

def top_five_ips(file_path)
  ip_counts = Hash.new(0)

  File.open(file_path, 'r').each_line do |line|
    fields = line.strip.split(',')
    ip = fields[0]
    count = fields[1].to_i
    ip_counts[ip] += count
  end

  sorted_ips = ip_counts.sort_by { |_ip, count| -count }

  top_five = sorted_ips[0...5]

  top_five.each do |ip, count|
    puts "#{ip}: #{count} requests"
  end
end

file_path = 'server_log.csv'
top_five_ips(file_path)


This version of the program uses the File class to open the input file and iterate over each line, splitting each line on commas to extract the IP address and request count. The rest of the logic is the same as before.

This program has fewer requirements than the original version, as it doesn't require the csv library. However, it may be less flexible and may not handle edge cases as well as the csv library.
