logic - Implementing 5-variable function using multiplexers -

-

If I have the 5-variable function (below) and I want to implement it using multiplexer, then I How to do (using the minimum possible multiplexer): 

  f (A, B, C, D, E) = A + CD + BD 'B'D + B'CE

This is homework, so do not provide solutions, a guide to how it works.

Thank you!

<5 5 variables with input from to 32 means 2 ** (32) multiplexer. convert these words binary numbers and keep the corresponding high. for B'CE we have: 

  ABCDX 0 1x1

This gives us 4 numbers, because We do not care 2. There are four numbers: 

  00101 = 5 00111 = 7 10101 = 21 10111 = 23

Hold inputs 5, 7, 21, and 23 high.

Repeat for the rest of the words.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
