how to generate permutations of array in python? -

-

I have an array of 27 elements, and I do not want to generate all the permutations of the array (27!) I need 5000 randomly selected permutations, any tip will be useful ...

using a permutation Repeat this operation in a loop and check the duplicate every time you use it to copy and archive the result (there is probably none) Will be). Your results set contains 5000 items, stop.

To address the point in the comment, it is based on Python and it has a duration of 2 ** 19937-1 , which is 27! , it should be appropriate for your use.

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 ....").

If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
