This problem is similar to "Contacts" application in phones.

We can use "Trie" - but this will be of space complexity BigO(n)
To reduce the space complexity we can use TST.

Data structure preferred .......but you may also implement in database using different queries ..

complexity as lesser as possible( within big O)?
take rows as many you required .......no constraint.
