level = min(x, y, n-x+1, n-y+1)
number = 2 * (level - 1) * n + 2 * (level - 1) * (n - 2 * (level - 1))

if(x == level):
number += y - level +1
elif(y == n-level + 1):
number += n - 2 * (level - 1) + x - level
elif(x == n-level + 1):
number += 2 * (n - 2 * (level - 1)) - 1 + (n - y) - (level - 1)
elif(y == level):
