Take a pen and paper, and in a place where nobody can interrupt you do the following exercise in your maximum speed. If you fail in the first tries DON’T give up, try again.
While you are doing this exercise, you should not look at what you would have written at any time!
Learn how the following strings are generated.
In the first string, write down from 0 to 9 but instead of zero write A.
In the second string, write down from 0 to 9 but instead of one write B.
In the third string, write down from 0 to 9 but instead of two write C.
...
In the 26th string, write down from 0 to 9 but instead of five write Z.
In the 27th string, write down from 0 to 9 but instead of six write A (after Z you should continue with A, B, C…).
In the 28th string, write down from 0 to 9 but instead of seven write B.
In the 29th string, write down from 0 to 9 but instead of eight write C.
…
As shown in the following, write until you would write Z instead of 7.
