    The sizes are 2**i for i in r (the argument, a list).

    The output displays i, 2**i, and the time to sort arrays of 2**i
    floating point numbers with the following properties:

    *sort: random data
    \sort: descending data
    /sort: ascending data
    3sort: ascending, then 3 random exchanges
    +sort: ascending, then 10 random at the end
    %sort: ascending, then randomly replace 1% of the elements w/ random values
    ~sort: many duplicates
    =sort: all equal
    !sort: worst case scenario
