+/**
+ * Once upon a time, on a way through the old wild west,…
+ * … a man was given directions to go from one point to another. The directions were "NORTH", "SOUTH", "WEST", "EAST".
+ * Clearly "NORTH" and "SOUTH" are opposite, "WEST" and "EAST" too. Going to one direction and coming back the opposite
+ * direction is a needless effort. Since this is the wild west, with dreadfull weather and not much water, it's
+ * important to save yourself some energy, otherwise you might die of thirst!
+ * How I crossed the desert the smart way.
+ * Write a function dirReduc which will take an array of strings and returns an array of strings with the needless
+ * directions removed (W<->E or S<->N side by side).
+ * The Haskell version takes a list of directions with data Direction = North | East | West | South. The Clojure
+ * version returns nil when the path is reduced to nothing.
+ * The Rust version takes a slice of enum Direction {NORTH, SOUTH, EAST, WEST}.
+ * Examples
+ * dirReduc(["NORTH", "SOUTH", "SOUTH", "EAST", "WEST", "NORTH", "WEST"]) => ["WEST"]
+ * dirReduc(["NORTH", "SOUTH", "SOUTH", "EAST", "WEST", "NORTH"]) => []
+ * Note
+ * Not all paths can be made simpler. The path ["NORTH", "WEST", "SOUTH", "EAST"] is not reducible.
+ * "NORTH" and "WEST", "WEST" and "SOUTH", "SOUTH" and "EAST" are not directly opposite of each other and can't become
+ * such. Hence the result path is itself : ["NORTH", "WEST", "SOUTH", "EAST"].
