Magic Square를 만드는 규칙이 있다. 8 1 6 3 5 7 4 9 2 위는 3*3의 Magic Square이다. 1부터 시작한다. 1의 오른쪽 대각선의 위치에 2를 쓴다. lst[0][1] ➡️ lst[2][2] lst[0][1]의 오른쪽 대각선은 lst[-1][2]이다. lst[-1][2] == lst[2][2] 2의 오른쪽 대각선의 위치에 3을 쓴다. lst[2][2] ➡️ lst[1][0] lst[2][2]의 오른쪽 대각선은 lst[1][3]인데 lst[1][3%3] == lst[1][0] 3의 오른쪽 대각선이 이미 숫자가 있어서 아래에 4를 쓴다. lst[1][0] ➡️ lst[2][0] 위와 같은 과정을 반복 🤗 나의 풀이 #!/bin/python3 import math import o..
