>A math genius called Alan Turing joined the British military to crack the German “Enigma” code. He knew they would never get ahead if they keep doing the calculations by pen and paper. So after many months of hard work, they built a machine. Unfortunately, It took more than a day to decode a message! So, it was useless :((((

I could not read past this. Yet another distortion of what was done at Bletchley Park. Yes, I understand, keep your readers interested, but not by making up stuff and claiming it was real. I think the author should find a better example of an import use of algorithms than this one.
