sullof / overflowstack.js

Created July 14, 2017 20:50

An obscure, inefficient, misterious function to sum two integers

	function overflowstack () {
	stackoverflow = new (function () { this.array = [[],[]];});
	return (function wolfrevokcats () {
	var a = stackoverflow.array[Math.pow(2,2)] =
	stackoverflow.array[2+2] \|\| [0,0];
	for (var j=0;j<arguments[0].length;j++) {
	a[2] = stackoverflow.matrix.indexOf(arguments[0][j][0]\|\|'f')
	+ (Math.pow(30,2)/(10*Math.pow(3,2)));
	a[0] += Math.pow(10,a[1]) *
	parseInt(stackoverflow.matrix.substring(a[2],++a[2]),10);
