I need to implement efficient search algoritham for comma separated list of MSISDN's that needs to be loaded in memory (left side of '|') character.
Followed by the comma separated series of MSISDN's that needs to be searched in the above huge list(millions)(right side of '|' character).
9845012345, 9845054321, 9845011111|9845011110, +919845012345, 09845054321
I want to implement this in c++ . Can anybody suggest what algoritham wiil be best suited for the same as here searched MSISDN can be expected in millions. I appreaciate your suggestions.
