Experiment5X / mismatch.cpp

Created May 7, 2014 21:17

Example usage of std::mismatch algorithm.

	#include <string>
	#include <iostream>
	#include <vector>
	#include <algorithm>

	using namespace std;

	int main(int argc, char *argv[])
	{
	vector<string> dogPeople = { "James", "Mary", "Tim", "Jane", "Greg" };

Experiment5X / Instruction2Bytecode.py

Created April 11, 2014 18:14

Convert an assembly instruction into its bytecode. It uses gas and otool, so this will only work on OS X, but it'd be pretty easy to modify it for linux.

	# USAGE INSTRUCTIONS
	# It's an interactive shell, where you have the following options...
	# - Just type in an assembly instruction in Intel syntax, and it'll spit out the bytecode
	# - Change the syntax to AT&T with the att command
	# - Change the syntax back to Intel with the intel command
	# - Quit with the q command
	import os
	import sys
	import tempfile

Experiment5X / PowerOfTwo.java

Created March 25, 2014 12:54

I saw an interview question on reddit to check if a given number is a power of 2 in one line. Here's a solution in Java.

	public static boolean isPowerOf2(int num)
	{
	return Math.log(num) / Math.log(2) == (double)(31 - Integer.numberOfLeadingZeros(num));
	}

Experiment5X / Student.cpp

Created January 5, 2014 22:45

Just a simple project I made to demonstrate some concepts in C++. Here's the video where I teach this project: http://www.youtube.com/watch?v=NIoEVxe-rpk

Experiment5X / Tweak.m

Created December 29, 2013 22:32

Change the secondary color theme in the music app on iOS 7 to be the aqua-blue color instead of that ugly pink.

	#import <UIKit/UIKit.h>

	@interface MAAppDelegate

	@property (nonatomic,retain) UIWindow * window;
	-(void)applicationDidFinishLaunching:(id)arg1;

	@end

	%hook MAAppDelegate

Experiment5X / remove_elements.cpp

Created December 7, 2013 17:34

The best way to remove elements from a vector, I got the concept from a video on MSDN by Stephan T. Lavavej about the associative containers in the stl.

	template <typename T>
	void remove_elements(vector<T> &vect, function<bool(T)> comparator)
	{
	auto newEnd = remove_if(vect.begin(), vect.end(), comparator);
	vect.erase(newEnd, vect.end());
	}

Experiment5X / Main.java

Created November 25, 2013 18:26

This program will solve any sudoku board that is in a text file. Numbers that aren't known should be represented as underscores and there shouldn't be any spaces. If there is more than one solution, then the first solution that is reached will be shown. Have fun.

	import java.util.*;
	import java.awt.*;
	import javax.swing.*;

	public class Main
	{
	public static void main(String[] args)
	{
	JFileChooser fileDialog = new JFileChooser();
	if (fileDialog.showOpenDialog(null) != JFileChooser.APPROVE_OPTION)

Experiment5X / MathFunctionLength.cpp

Last active December 27, 2015 17:49

This function will get the approximate length of a mathematical function if it were stretched into a straight line. This works by splitting the curve of the function up into a bunch of right triangles and then adding their hypotenuses together. The precision argument simply dictates the amount of triangles used. The more there are, the more accu…

	#include <iostream>
	#include <functional>
	#include <algorithm>

	using namespace std;

	double GetFunctionLength(double start, double end, function<double(double)> mathFunc, int precision)
	{
	if (precision < 1)
	return 0;

Experiment5X / diabolo.py

TechGame programming challenge

	import sys

	def PrintDiaboloLine(centerLen, totalLen):
	endLen = (totalLen - centerLen) / 2
	print endLen * '.' + (centerLen * '@') + endLen * '.'

	def PrintDiabolo(width, height, iteration):
	if (iteration * 2) + 1 >= height:
	PrintDiaboloLine(2, width)
	return

Experiment5X / square.c

	void PrintStarLine(int len)
	{
	for (int i = 0; i < len; i++)
	printf("*");
	printf("\n");
	}
