## Background: PacMan Moves
At each intersection, check if there is a ghost directly inline with that path.
If the path is free of ghosts, you are allowed to turn there. And if PacMan is moving in a direction, and a ghost enters
his path, then pacman will reverse.
At each intersection, check if there is a ghost directly inline with that path. If the path is free of ghosts, you are
allowed to turn there. And if PacMan is moving in a direction, and a ghost enters his path, then pacman will reverse.
For example if pacman is at an intersection and can go either right or up, and there is a ghost in the path going right,
then pacman will go up. Then while pacman is going up, a ghost enters that path, pacman will go back.

## Exercise
1. Implement `PacManAI::pelletClosestToPacman` and test your implementation with the test
1. Implement [PacManAI::pelletClosestToPacman](../../../lib/PacManAI.cpp) and test your implementation with the test
in [testPacmanAI.cpp](../../../test/testPacmanAI.cpp) called _"Find pellet closest to pacman"_
2. Implement `PacManAI::isValidMove` and test your implementation with the test
*Hint*:
```cpp
GridPosition PacManAI::pelletClosestToPacman(GridPosition pacmanGridPosition,
std::vector<GridPosition> & pellets) {
return {0, 0};
}
```
2. Implement [PacManAI::isValidMove](../../../lib/PacManAI.cpp) and test your implementation with the test
in [testPacmanAI.cpp](../../../test/testPacmanAI.cpp) called _"Is valid move"_
3. Implement `PacManAI::optimalDirection` and test your implementation with the test
*Hint*:
```cpp
bool PacManAI::isValidMove(const Move & move) {
return false;
}
```
3. Implement [PacManAI::optimalDirection](../../../lib/PacManAI.cpp) and test your implementation with the test
in [testPacmanAI.cpp](../../../test/testPacmanAI.cpp) called _"Is optimal direction"_
*Hint*:
```cpp
Direction PacManAI::optimalDirection(const std::array<Move, 4> & moves) {
return Direction::NONE;
}
```
