alt Hacker NewsBig O basically drops constants
O(2n+1) = O(2n) = O(n)
o(2n+1) > o(2n) > o(n)
Both define upper boundary, but big O can read like "the function is generally proportional to ___" and little o can read like "the function is never more than _____"

that's not the convention I know... (from CLRS algorithms book).
Big O is sort of like <=. little o is sort of like <.
