w****g 发帖数: 44 | 1 If there are a lot of different types of A,B .... molecules in the system,
and I want to quickly get all the molecules of type A,do anyone know how can
I realize that ??
This is a kind of pattern matching problem ?
My thought is:
1. First transfer all molecule structures into a string and store them.
2. Then search for the strings for the desired string.
Any body has a better idea? or where can I find such an algorithm ?
Any clues are highly appreciated. |
