- // ZigZag Transform: Encodes signed integers so that they can be effectively
- // used with varint encoding.
- //
- // varint operates on unsigned integers, encoding smaller numbers into fewer
- // bytes. If you try to use it on a signed integer, it will treat this
- // number as a very large unsigned integer, which means that even small
- // signed numbers like -1 will take the maximum number of bytes (10) to
- // encode. zigZagEncode() maps signed integers to unsigned in such a way
- // that those with a small absolute value will have smaller encoded values,
- // making them appropriate for encoding using varint.
