Is unsigned integer subtraction defined behavior?
...nt five = 5, seven = 7;
unsigned int a = five - seven; // a = (-2 % 2^32) = 4294967294
int one = 1, six = 6;
unsigned int b = one - six; // b = (-5 % 2^32) = 4294967291

What would cause an algorithm to have O(log n) complexity?
...o have that log2 16 = 4. Hmmm... what about 128?
128 / 2 = 64
64 / 2 = 32
32 / 2 = 16
16 / 2 = 8
8 / 2 = 4
4 / 2 = 2
2 / 2 = 1
This took seven steps, and log2 128 = 7. Is this a coincidence? Nope! There's a good reason for this. Suppose that we divide a number n by 2 i times. Then...
