Algorithm

Question

why we need to analyze algorithm in terms of time and space???!

Answer 1

So we can check (and then choose) which amongst the variants is the optimal one that will be the chosen algorithm?

Answer 2

Imagine there are two text editors, you have to decide which one to buy.

Editor one takes 3 seconds to open any new window.

Editor two takes not even one second.

Otherwise there's no difference.

Which one will you buy?
