You have to generate a convex polygon which

- has N points
- each Xi is distinct and is between 1 and N
- Each Yi is positive and less than 10
^{10}

There can be many many convex polygons that fits this description. You have to print any one of them.

The only line in input is N (3 ≤ N ≤ 100000).

Print N lines. Each line will contain two integers Xi and Yi.
