Computational complexity of Fibonacci Sequence
...is asymptotically O(2n). You can then prove your conjecture by induction.
Base: n = 1 is obvious
Assume T(n-1) = O(2n-1), therefore
T(n) = T(n-1) + T(n-2) + O(1) which is equal to
T(n) = O(2n-1) + O(2n-2) + O(1) = O(2n)
However, as noted in a comment, this is not the tight bound. An interestin...

Why can't (or doesn't) the compiler optimize a predictable addition loop into a multiplication?
...that the address of the array was saved in a register so it could optimize based upon that, but the debugger simply knew the address of a constant. Thus, before a statement MyArray[0] = 4; I could check the adddress of MyArray, and look at that location before and after the statement executed; it w...
