I was having the same problem, it turned out to be when the vector is empty and we subtract 1 from its size, the comparison in the for loop doesn't work as we expect because v.size() returns an unsigned, and the result of 0 - 1 ends up beign a big positive number instead of -1

Oh man, I love c++ hahah

So I guess I'm missing how to create the sensors database for the agent, and how to query it properly.

Hey guys, can someone give me a hint on this one? I've been trying it for quite some time.
I'm using a BFS, but at this point I'm not quite sure if this is a good approach. A DFS would be any better?

Edit: scrolling down I saw my old post, from 6 months ago, hahah wow

Lol, ty

I completely missed the point, I know that he can reach the gold, but the agent itself doen't know the entire layout of the map.

Could someone please explain to me why these should be false? Can't the agent get to the gold safely?

Can you elaborate more on this, please? I'm getting the same error

Solved, idk why but the problem was that I was using vector reserve.

This doesn't make any sense, are the matrices being converted to a string when checking the test cases?
They should compare equal, given that all numbers match, independently of these weird spaces.

C++

It looks like this without the [

       1,           2,           3 ],
       8,           9,           4 ],
       7,           6,           5 ]

Hi everyone, I am getting this strange behavior:

Expected: equal to [
[ 1, 2, 3 ],
[ 8, 9, 4 ],
[ 7, 6, 5 ]
]
Actual: [
[ 1, 2, 3 ],
[ 8, 9, 4 ],
[ 7, 6, 5 ]
]

Does anyone know why my solution has those spaces before the numbers? Ty

PS.: They don't actually show up when I publish the comment.

Seeing this I feel very embarrassed for my solution hahaha
Nice job man
