obikag / CompareTables.lua

Last active December 20, 2015 03:59

Function to compare tables based on values within each table. Sequence of values in each table is not taken into consideration. This function returns true if all of the values in each of the tables match.

	--Method to compare tables
	function compare_tables(table1,table2)
	temp = {}
	if #table1 ~= #table2 then return false end
	for _,v1 in pairs(table1) do
	for _,v2 in pairs(table2) do
	if v1 == v2 then
	table.insert(temp,v1)
	break
	end

obikag / CompareTuples.py

Created July 24, 2013 01:20

Function to compare tuples based on values within each tuple. Sequence of values in each tuple is not taken into consideration. This method returns true if all of the values in each of the tuples match.

	# Method for comparing two tuples
	def compare_tuple(tuple1,tuple2):
	temp = []
	if len(tuple1) != len(tuple2): return False
	for val1 in tuple1:
	for val2 in tuple2:
	if val1 == val2:
	temp.append(val1)
	break
	return (len(temp) == (len(tuple1) and len(tuple2)))

obikag / Simple-CSV.lua

Created July 31, 2013 00:52

Simple Lua Object that can read and modify a CSV file. Strings containing a comma (,) are not supported.

	--Initialise
	SimpleCSV = {}
	SimpleCSV.__index = SimpleCSV

	--Create new object
	function SimpleCSV.new()
	self = setmetatable({},SimpleCSV)
	self.csv_table = {}
	return self
	end

obikag / fibonacci.lua

Created August 13, 2013 23:10

Fibonacci Number methods done in Lua. First two methods calculates the Fibonacci number (n), while the last method prints the Fibonacci number sequence 'n' times.

	-- Recursive Method calculating Fibonacci Number for n
	function fibRecursion(n)
	if n == 0 then
	return 0
	elseif n == 1 then
	return 1
	else
	return fibRecursion(n-1) + fibRecursion(n-2)
	end
	end

obikag / Prime.lua

Created September 19, 2013 00:03

Prime number functions done in Lua. First function determines if a number is prime, while the second function print to screen the first 'n' prime numbers. View comments for more information.

	---Function to determine if a number is a prime number
	function isPrime(num)
	if num <= 0 then
	print("Number must be a positive integer greater than zero")
	return false
	elseif num == 1 then return true end
	--[[Prime number is divisable by itself and one,
	so we check for other factors between the prime number and one. (1 < x < num)
	]]
	for x = num-1,2,-1 do

obikag / PascalTriangle.lua

Last active December 23, 2015 23:09

Pascal's Triangle calculated using a recursive function in Lua.

	--Recursive function to create the mathemeatical series
	function pascal(col,row)
	if(col == 0) or (col == row) then return 1
	else return pascal(col-1,row-1) + pascal(col,row-1)
	end
	end

	--Prints Pascal's Triangle to the 'n'th row
	function PascalTriangle(num)
	if (num <= 0) then print("Number must be greater than zero") return end

obikag / ROT13.lua

Created October 18, 2013 02:39

ROT13 substitution cipher implemented in Lua. ROT13 function encrypts and decrypts a given string. Special characters and numbers are not encrypted with this cipher.

	--Create a table to store the cipher
	cipher = {
	A="N",B="O",C="P",D="Q",E="R",F="S",G="T",H="U",I="V",J="W",K="X",L="Y",M="Z",
	N="A",O="B",P="C",Q="D",R="E",S="F",T="G",U="H",V="I",W="J",X="K",Y="L",Z="M",
	a="n",b="o",c="p",d="q",e="r",f="s",g="t",h="u",i="v",j="w",k="x",l="y",m="z",
	n="a",o="b",p="c",q="d",r="e",s="f",t="g",u="h",v="i",w="j",x="k",y="l",z="m"
	}

	--Function encrypts and decrypts using ROT13
	function ROT13(str)

obikag / XorCipher.lua

Created November 21, 2013 21:59

XOR Cipher in Lua. See comments for more information.

	cipher = "10101111" -- must be eight digit binary number

	--Returns the XOR of two binary numbers
	function xor(a,b)
	local r = 0
	local f = math.floor
	for i = 0, 31 do
	local x = a / 2 + b / 2
	if x ~= f(x) then
