reverse-complement benchmark ≈240MB N=25,000,000

Each chart bar shows how many times more Code, one ↓ reverse-complement program used, compared to the program that used least Code.

These are not the only programs that could be written. These are not the only compilers and interpreters. These are not the only programming languages.

Column × shows how many times more each program used compared to the benchmark program that used least.

 reverse-complement benchmark : Read DNA sequences - write their reverse-complement

You can write your own program for this task and contribute to the benchmarks game by following these general instructions.

More specifically:

diff program output for this 10KB input file (generated with the fasta program N = 1000) with this output file to check your program is correct before contributing.

We are trying to show the performance of various programming language implementations - so we ask that contributed programs not only give the correct result, but also use the same algorithm to calculate that result.

We use the FASTA file generated by the fasta benchmark as input for this benchmark. Note: the file may include both lowercase and uppercase codes.

Each program should

We use these code complements:
