Note: Work in JS
This code doesn't work as fast as we would like. Can you make it 3 times faster, while having exactly the same output ? (in the same order).
Constraint: The machine on which the code runs has only one core.
When rating the answer, we care about what was changed in the code, rather than the execution speed of the program (as long as it runs in the required time).
Note: data.tar.gz must be extracted before starting the test, by running the
following command: tar xvzf data.tar.gz.
The test can be done in either PHP, Go, or Javascript.
# PHP:
time php test1.php ./words ./test1.in > test1.out
# Go:
go build test1.go && time ./test1 ./words < test1.in > test1.out
# NodeJS:
time node test1.js ./words < test1.in > test1.out# Check output:
diff -u test1.exp test1.out && echo OK
