### Code

```n, t = map(int, input().split())
coords = []

for i in range(t):
coords.append(map(int, input().split()))

for y, x in coords:
if x + y >= n+1 and x > y : # Right triangle
corner_tmp = (x-n/2-1)*2
corner_val = n**2-(corner_tmp*(corner_tmp+1))
val = corner_val + n-x+1 - y
elif x <= y and x + y > n+1 : # Bottom triangle
corner_tmp = (y-n/2-1)*2+1
corner_val = n**2-(corner_tmp*(corner_tmp))
val = corner_val - y + x
elif x + y <= n+1 and x < y+1: # Left triangle
corner_tmp = (n/2-x)*2+1
corner_val = n**2-(corner_tmp*(corner_tmp+1))
val = corner_val - n+x-1 + y
elif x >= y+1 and x + y < n+1 : # Upper triangle
corner_tmp = (n/2-y)*2
corner_val = n**2-(corner_tmp*(corner_tmp))
