#1 - The Role of Algorithms in Computing

(I am not accountable for mistakes in the calculations since it's past 2am :laughing:)

PS1: see the [README](https://github.com/rmascarenhas/ita#introduction-to-algorithms)
PS2: get used to LATEX.
PS3: I'm pasting the compiled version here, but you should only see it after you open your own pull request.

Hum, got it, but I think that we would be talking on a complexity of `f(n) = n + c` where `c` is the constant time to remove the element.
