I want to ask for your opinion of a search algorithm.
Suppose we have 3 records containing the following data:
Record 1: 100 200 300 400 500
Record 2: 100 300 500
Record 3: 100 400
Then what is the fastest approach to find how many data coexist in both 3
records? Like this example data 100 coexist in both 3 records. I use
exhaustive search so that the performance is very slow. I hope you can give
some opinions to me.
