Tak performed the following action N times: rolling two dice.
The result of the i-th roll is D_{i,1} and D_{i,2}.
Check if doublets occurred at least three times in a row.
Specifically, check if there exists at lease one i such that D_{i,1}=D_{i,2}, D_{i+1,1}=D_{i+1,2} and D_{i+2,1}=D_{i+2,2} hold.

-----Constraints-----

- $1\leq D_{i,j} \leq 6$
- All values in input are integers.

-----Input-----
Input is given from Standard Input in the following format:
