원형파이는 컴퓨터를 보고 있었다.
그런데 작은 날벌레가 컴퓨터 화면에 와서 앉았다.
원래라면 호들갑을 떨 원형파이인데, 갑자기 호기심이 생겼다.
"내가 잡기는 싫으니까, 다른 사람한테 위치를 알려주고 잡으라고 해야지~"
이렇게 해서 원형파이는 좌표계를 만든 데카르트와 같은 상황이 되었다.
날벌레는 다리가 6개라 하자. 그리고 너무 작아서 어떤 칸을 차지할 수 있는 건 다리밖에 없다.
격자로 나누는데, 위치를 격자가 아니라, 격자 내부의 공간으로 나타낸다고 하자.
| 1,1 |
1,2 |
1,3 |
1,4 |
1,5 |
| 2,1 |
2,2 |
2,3 |
2,4 |
2,5 |
| 3,1 |
3,2 |
3,3 |
3,4 |
3,5 |
| 4,1 |
4,2 |
4,3 |
4,4 |
4,5 |
| 5,1 |
5,2 |
5,3 |
5,4 |
5,5 |
이런 식의, 좌표계가 아닌 격자계라는 것이다.
그렇다면, 날벌레의 위치는 최소 몇 개의 격자로 나타낼 수 있을까?
최대로는 몇 개의 격자로 나타내야 할까?
