Random Algorithm Number & Letter

For Number

The Algorithm Method is Pseudo Random Number Method.

This is i make for number algorithm number, and the idea from this picture

A lot of smart people actually spend a lot of time on good ways to pick pseudo-random numbers.  They try a bunch of different complicated formulas, and try to make sure that patterns don’t pop up.  But we can build a simple one pretty easily to pick pseudo-random numbers from 1 to 10.  Here it is, in the programming language Haskell:

Example :

1 --> 7

2 --> 3

3 --> 10

4 --> 6

5 --> 2

6 --> 9

7 --> 5

8 --> 1

9 --> 8

10 --> 4

How can that's number changes, it's simple, just used this algorithm : random n = (7 * n) mod 11

So the calculation is like this :

random 1

= (7 * 2) mod 11 

= 14 mod 11

make it simple :

14  mod 11

= 14/11 = 1.272...

= (1.272...)-1

= (0.272...)*11

= 3

The result is 3
