increment numbers in list comprehension

I am new to python. I am learning list comprehension to shorten my code to minimum. But I am unable to incremnent inside a list comprehension. Like this code:

n = 0; c = 0
for i in range(input()):
   m = map(int,raw_input().split())
   [n+=1 if m[0] > m[1] else c+=1]
print ['N'. 'C'][c > n]

My input:

3
3 4
2 4
2 5

The output should be:

N
