[[Artificial intellegent] strange bug problem c++

mahmoud2592 (27)
I am trying to make a BotClean Partially Observable,but there is a bug in between line 21 to line 36,Although at debuging j<=newposy but at the watches window j exceed new_posy by 1.
for example when I entire this input

0
1
-b---
-d---
---d-
---d-
--d-d

input 0 1 are for the position of the bot"b","d" is for dirty position
,at watches window
i=> 0 0 0 0 1 1
j=> 0 1 2 3 0 1
new_posx=1
new_posy=2

at the fourth iteration i=0 and j=3,why j=3 it exceed new_posy by 1 ,any help please !!??
