The first method will be faster - but IMO it's not the right way of doing it. I'm in agreement with tehvan about that.
The first optimization would be splitting the id into three different fields: one for type, one for size, one for the current id ending (whatever the ending means) If you really want to keep the current structure, go for the result straight away (option 1).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
