Created January 5, 2017 21:29
["NORTH", "SOUTH", "SOUTH", "EAST", "WEST", "NORTH", "WEST"] You can immediatly see that going "NORTH" and then "SOUTH" is not reasonable, better stay to the same place! So the task is to give to the man a simplified version of the plan. A better plan in this case is simply: ["WEST"]
def dirReduc(arr)
check = {north: "SOUTH", south: "NORTH", east: "WEST", west: "EAST"}
res = []
for i in 0...arr.length
if res.last && check[res.last.downcase.to_sym] == arr[i]
res.pop
