Task: You are a drone operator. Your task is to reforest one hard reachable area with your drone. Area has a shape of a square with nine blocks (3x3).
First you need to plant oaks on blocks numbered with prime numbers equal or greater then 3, from the lowest to the biggest. Afterwards, you continue planting pines on blocks numbered with even numbers, starting in the block with the lowest number and continuing to the biggest.
In the end you will plant willow on the remaining blocks, starting with the block closest to the one you were in the moment you planted last pine.
Draw a path your drone will follow in the process of planting trees.
Background: algorithms can operate drones, robots and all machines that can help replace people in difficult jobs. Mathematics and physics are basis for understanding how to create and programme machines.
