Hello @anshulgurawalia last call should from helper to destination.
corrected code:

#3

but in my case helper is b and destination is c and a is the source so i made last call
move( n-1, b, a ,c)
please tell why you change it to move(n-1, c , b ,a )

@anshulgurawalia because in your first call you are treating a as source and c as helper and then b as the destination.
so you are mixing both the things.
