    I am Spanish (I am using GTranslate for this comment), and I have a lot to thank for this video. It has helped me more than my university's own to understand how to solve the fast exponentiation algorithm. A lot of thanks!

    Thank you very much for showing us this easier way to find modulus. Before that, we could not practice text encrypting algorithms using C++. But now we can.

      one can encrypt text just by xor it with the key.. its unbreakable to some extent..

    Hi. I'm not that bright. How do we easily calculate 240^2(mod14)=4?

    • @guilhermefranco2949
      @guilhermefranco2949 2 года назад +4

      Notice 14 * 17 = 238, such that 240 is 2 mod 14, then we can plug in to find 240^2 = 2^2 = 4 (mod 14).

    • @syedrizvi1704
      @syedrizvi1704 2 года назад +3

      240 mod 14 = 2 because 240=14*17+2. Now taking square on both sides, you will get 240^2 mod 14 = 2^2. Therefore, 240^2 mod 14 = 4. Hope this helps!

      There is a rule if
      a mod b congurent c
      d mod b congurent e
      ad mod b congurent ce
      240mod14 (14 × 10 + 14 × 5 + 14 × 2 = 238) congurent 2
      240×240mod14 congurent 2×2

    2:06 if in the first column I had 0 instead of 1, should I always put 240 or 1?

    • @georgeallen7487
      @georgeallen7487 2 года назад +6

      There are infinite zeros before every binary expansion of an integer, but they are just not written because they carry no information. It follows that the first column will always be one, for all numbers other than zero.
      For a concrete example take the number twenty. I can write it 20 or 020 and it represents the same integer. Analogously I can write 010(base b) and 10(base 2) and they have the same value.

      Divide 2^2 by 14 and find the remainder. So, 4 mod 14 = 4
