What is wrong with my implementation of HDELIVER?

Code : http://www.codechef.com/viewsolution/3934828

Initially I got TLE but after using better implementation, I am getting Wrong Answer.

this is mostly one of the errors…

you are not marking the current element i.e. the kth element as visited as not marking its color!!!

this should be added

color[k]=iter;

EDIT 1:

w/o that try putting this case u will get all ans as YO but it should be NO…
