The most efficient way to implement an integer based power function pow(int, int)
...tion chain for a¹⁵ above, the subproblem for a⁶ must be computed as (a³)² since a³ is re-used (as opposed to, say, a⁶ = a²(a²)², which also requires three multiplies).

Difference between Big-O and Little-O Notation
...
x² ∈ O(200 * x²)
The following are true for little-o:
x² ∈ o(x³)
x² ∈ o(x!)
ln(x) ∈ o(x)
Note that if f ∈ o(g), this implies f ∈ O(g). e.g. x² ∈ o(x³) so it is also true that x² ∈ O(x³), (again, think of O as <= and o as <)
