### Code

```inn = input().split(' ')
n = int(inn[0])
t = int(inn[1])

summat = []
last = n

for i in range(n//2):
p = last+last-1+last-1+last-2

if len(summat) > 0:
p = summat[i-1]+p

summat.append(p)
last -= 2

summat=[0]+summat

for _ in range(t):
inn = input().split(' ')
y = int(inn[0])
x = int(inn[1])

nth = min(y, x)

up = y-1
bottom = n-y
left = x-1
right = n-x

mins = min(up, bottom, left, right)
nth = mins + 1

result = summat[mins]
last = n-(2*mins)

if mins == left:
print(result+(y-nth)+1)
continue

result += last

if mins == bottom:
print(result+(x-nth))
continue

result += last-1

if mins == right:
print(result+n-y-mins)
continue

result += last-1

if mins == up:
print(result+(n-x)-mins)
