Description

In the Tsinghua campus, life would be very inconvenient without a bicycle when attending classes or handling errands. However, in reality, biking is not always faster for every errand because it involves time spent finding a bike, unlocking it, parking, and locking it again, which takes some extra time.

Assume the time to find a bicycle, unlock it, and mount it is 27 seconds; the time to park and lock the bicycle is 23 seconds; walking speed is 1.2 meters per second, and biking speed is 3.0 meters per second.

Given different distances for an errand, determine whether biking or walking is faster. If biking is faster, output "Bike"; if walking is faster, output "Walk"; if they are equally fast, output "All".

Input Format

The input consists of a single line containing an integer, representing the distance (in meters) to travel for the errand.

Output Format

Output a single line: if biking is faster, output "Bike"; if walking is faster, output "Walk"; if they are equally fast, output "All".
