WebBradley Reynolds. The word problem states that the computer can sort n values in k * n^ (1.5) microseconds. This gives us an equation of time to sort = k * n^ (1.5). We are then given that it can sort one million values in half a second, this means our time would equal 500,000 microseconds (one million microseconds in a second). So we can then ...
