This is the question. https://codeforces.me/contest/1974/problem/E
AC submission -> https://codeforces.me/contest/1974/submission/287177874
WA submission -> https://codeforces.me/contest/1974/submission/287176403
In both my submissions, i have the exact same approach, only diff being in 1 case i use the current dp state to update the next dp states(in the WA submission) and in the AC submission i use previous dp states to update current dp states.
Where am i going wrong?
*Edit -> Resolved

Its pretty obvious from my code what i am trying to do. My Question is that is the logic correct? Where am I going wrong?
I just take cases of whether the door is locked or not and accordingly I build the adj list for the corresponding switch combinations.
*Edit -> Resolved now.
