### Code

```n, t = [int(x) for x in input().split()]
#t = int(input())
y = []
x = []
def spiral_matrix(n):
m = [[0] * n for i in range(n)]
dx = [1, 0, -1, 0]
dy = [0, 1, 0, -1]
x, y, c = -1, 0, 1
for i in range(n + n - 1):
for j in range((n + n - i) // 2):
x += dx[i % 4]
y += dy[i % 4]
m[x][y] = c
c += 1
return m

for i in range(t):
x1,y1 = [int(x) for x in input().split()]
x.append(y1)
y.append(x1)
a=[]
for i in spiral_matrix(n): a.append(i)
for j in range(t): print(a[y[j]-1][x[j]-1])```
