PROGRAMMING:ZF series lost

Walking out of the cave, ZF didn't see the gentle sunshine, surrounded by a thick fog, but he found the number left by his ancestors at his feet, and he learned the mystery of the thick fog through the number.
If the number left by our ancestors is 0 for 4, it means that it is the right way to go from north. 1 corresponds to the south, 2 to the East, and 3 to the West.
In English
