is there any function which gives us max of values in terms of strings?

You can use LASTNONBLANK to return the 'maximum' of a text column.
See this article on SQLBI:

Hi @Anonymous,
That's right, LASTNONBLANK/FIRSTNONBLANK order text lexicographically.
If you want the text value with greatest length, you can do this or something similar:
Longest Text Value = CALCULATE ( LASTNONBLANK ( MyTable[TextColumn], 0 ), TOPN ( 1, VALUES ( MyTable[TextColumn] ), LEN ( MyTable[TextColumn] ) ) )
If there are ties, they are broken by LASTNONBLANK.
