rkjha / frequency_db.rb

Last active December 18, 2015 00:09

First ruby program reads a file containing numbers (separated by space), and calculates the each occurrence of the number (a.k.a frequency distribution). Second one, simply prints a number from 1 to n with the condition (if it's divisible by 3 then Hip, divisible by 5, then Hop, and if it's divisible by both 3 and 5, then it prints Whazaa)

	# assuming the file is there in the same dir as numbers.txt

	file = File.open("numbers.txt", 'r')
	frequency_db = Hash.new

	file.each_line do \|line\|
	line_n = line.split
	line_n.each do \|n\|
	if frequency_db.has_key?(n)
	frequency_db[n]+=1
