The objective of the number drop game is to try and get a row of numbers in order by selecting certain ones that you want to drop to the end of the line. When you drop more than one number they move to the end while still keeping their relative order and the numbers you didn't drop move to the front while still keeping their relative order. You keep doing that until all the numbers are in order.

Solve these in the fewest moves possible:

1)1 3 5 7 9 2 4 6 8 10
2)10 9 8 7 6 5 4 3 2 1

For ex: 34521

drop 34 = 34521 -> 52134
drop  2 = 52134 -> 51342
drop 34 = 51342 -> 51234
drop  5 = 51234 -> 12345

I believe Eric O. has tried his best to solve the question.

I do not know whether the following method is the shortest way;

10 9 8 7 6 5 4 3 2 1

Drop all odd numbers first in such a way that begins with small number, 1, first and after that followed by 3 & then 5 & then 7....  I do it in such a way since the question does not mention we could not do so.

Drop all even number first in such a way that begins with small number, 2, first and after that followed by 4, & then 6..
