-- Here I sneak around a bit, and realize the problem is well defined --
|
||||
-- (and solved!) already: it's called the Chinese Remainder Theorem --
|
||||
-- https://en.wikipedia.org/wiki/Chinese_remainder_theorem --
|
||||
-- -------------------------------------------------------------------------- --
|
||||
-- Apllying the theorem allows to reduce a system of equation on x: --
|
||||
-- --
|
||||
-- x ≡ a1 (mod n1) --
|
||||
-- · --
|
||||
-- · --
|
||||
-- · --
|
||||
-- x ≡ ak (mod nk) --
|
||||
-- --
|
||||
-- to a single equation: --
|
||||
-- --
|
||||
-- x ≡ as (mod ns) --
|
||||
-- --
|
||||
-- It relates to the buses schedules in the following way: t is x, the bus --
|
||||
-- number is the modulo factor (since a bus comes *every* ni) and subsequent --
|
||||
-- additions to t (for other buses) is (-ai), so, for a but coming at --
|
||||
-- t+ai, one would write x ≡ -ai (mod ni) --
|
||||
-- --
|
||||
-- I chose to encode ai and ni as a tuple (ai,ni), named startAndIds --
|
||||
-- --
|
||||
-- Basically, we're creating a “chinese” function: --
|
||||
-- --
|
||||
-- chinese :: (Int,Int) -> (Int,Int) -> (Int,Int) --
|
||||
-- --
|

-- Then, given a list [(Int, Int)] we can fold over it to obtain the solution --

-- --
