- Algorithm
- using double loop to search all map array.
- using recursive function(dfs) to find all cases.
- Time Complexity
- i searched all array entities so O(n^2).
- i repeated solution function recursively, and each case has 4 cases so O(4^n).
i used CCTV class which has its directions array, rotation function, and inspection function. i used common dfs to solve this problem.

재귀함수 안에서 배열 선언되면 깊이 못들어가는건 설명했으니까 알거고,
대안으로 이런걸 전역변수로 선언해서 재활용하는걸 공부하면 좋을듯
