Comparison Sort (SORT):
Given a sequence of elements of any (uniform) type and a
comparison function over the elements, sort the elements into
ascending order. The elements consists of a key and possible
auxiliary data, and the comparison function must define a total order
over the keys. The sort need not be stable. The code must not take
advantage of the specific type beyond the comparison function.
Input and Output File Formats
The input and output data need to be in the sequence file
format, both with the same element type. The output file
must be in sorted order with respect to the given comparison function.
Default Input Distributions
Each distribution should be run for
n=10,000,000. Currently
none of the inputs use auxiliary data. The weight of each input
for the purpose of reporting average times is given in parentheses.

(1) Double precision floating point numbers generated uniformly at
random from the range [0:1].
randomSeq t double <n> <filename>

(1) Double precision floating point numbers generated at random
with repeats appearing in an exponential distribution.
exptSeq t double <n> <filename>

(1) Double precision floating point numbers from an almostsorted distribution.
almostSortedSeq t double <n> <filename>

(3) Strings from a trigram distribution.
trigramSeq <n> <filename>

(3) Strings from trigram distribution, but order randomized after
allocation. In particular after the data is read in, the pointers to
the strings have to be randomly shuffled (the shuffling should not be
included in timing). The purpose of this test is to see how the sort
does when strings are not allocated adjacently with respect to the
input pointers.
