The code looks fine.
For speed, you could insert the following just before the while-loop:
while (n >= 256) {
n >>= 8;
result += 8;
}
Am not sure the "numbits" is the right-name. Is there precedent in
other languages or texts on bit-twiddling techniques? For
numbits(0b0100), I could forsee people predicting a result of 4, 3, or 1
depending on their world-view of what numbits might mean. Personally, I
tend to think in term of high-bit location or somesuch. |
