Q:

Thanks in advance!!

Given a string, find the rank of the string amongst its permutations sorted lexicographically.

Note that the characters might be repeated. If the characters are repeated, we need to look at the rank in unique permutations.

Look at the example for more details.

Example :

Input : 'aba'

Output : 2

The order permutations with letters 'a', 'a', and 'b' :

aab

aba

baa

The answer might not fit in an integer, so return your answer % 1000003
