* Optimized LUT requires marginally more arithmetic operations over other variants
Average cycle count: N/A (not fully implemented)
### bsrt2.uc
A fourth iteration developed in parallel with *sort3* as a proof-of-concept of
the recently designed lookup-table replacement for hashing. This version is an
almost direct copy of *bsrt*, except without a LUT, a K1 jump-table and absolute
sizes in the bucket headers (as opposed to a pointer to the last element of a
bucket).
Pros:
* Highly optimized K1 jump-table
* Subroutined jump-table for possible reuse elsewhere
* 13 elements per bucket (+1 over *bsrt*)
* Low instruction count
Cons:
* Only sorts one element per iteration
Average cycle count: 1050
