"""Bisect based formula testing.

Implements bisect_lt, bisect_le, bisect_ge, bisect_gt from scratch using `yfun`
# http://code.google.com/codejam/contest/2418487/dashboard
>>> r, t = 10**16, 10**18
>>> yfun = lambda x: (2*(10**16) + (2*x) -1) * x
Given bisect_le(yfun, y, range(N))
>>> bisect_le(yfun, t, range(t))
