prob: https://leetcode.com/problems/unique-paths/submissions/

code: https://ide.codingblocks.com/s/421826

the code is working but I wanted to know that why do I have to pass the arguments as n-1 and m-1 and not simply as m and n.

#2

Hello @raghav007 you have to pass the parameters as m-1 and n-1 because the indexing is 0 based so if you m is 3 and you start from 0 then 0 1 2 will constitute for the same number of elements but indexing 0 based so we will compute for final value as m-1 and n-1.

#3

alright but when I make the case as if( m==1 || n== 1) return 1 and I pass in n, and m then it does not gives the right answer

#4

in leetcode you dont have main function with you so there is possibility that might be they are passing m-1 only and then if you are using base case for m==1 then you are not calculating completely you have returned in between only.
