That only considers the purchase cost. The operations costs makes sand an even worse proposal.

Why? Just because something is old doesn't mean it is bad. Just because it is new doesn't mean it is good.

My sensitive point is price-per-bit. So HDDs win.

Nonsense. My entire lair has no SSDs, they are too small for the price (and really hard to ensure erasure).

Make sure to buy more shares in energy companies when the next prime is found.

I think the salient point here to answer the question is that for the most part no assignments win money unless you are very very lucky to find the needle in the haystack.

There are more even numbers than odd numbers

Every odd number is half of an even number.

Some even numbers are not double an odd number.

Therefore there are more even numbers than odd numbers. :showoff:

Yes.

The first number to match the criteria is 100 = 1*99^1+1
Then 200 = 1*198^1+2
Then x*100 = 1*(99x)^1+x
etc.

So all you have to do is check that the number is divisible by 100.
