Question (1/5): We have a robot that can pick up blocks from a stash, move them horizontally, and lower them in place. There are 10 positions available to lower blocks, numbered from 0 to 9. Each position can hold up to 15 blocks. [Two diagrams with the hexidecimal axis of x-axis [0-9], and y-axis [1-F] and arbitrary placement of blocks in diagram] The robot understands the commands 'P', 'M' and 'L': P: Pickup from the stash and move to position 0 M: Move to the next position L: Lower the block The robot is safe to operate and very forgiving: • There are always blocks in the stash (Pickup will always get a block). • If the robot already holds a block, Pickup will reset the robot to position 0. • The robot will not go beyond position 9. Trying to Move it further does nothing. • Lowering a block on a pile of 15 blocks does nothing (and the robot will keep any block it holds). • Lowering without a block does nothing. • The robot ignores any command that is not 'P', 'M' or 'L' Implement a function that takes a [String] of commands for the robot. The function should output a [String] representing the number of blocks (in hexadecimal) at each position after running all the commands. This all has to be implemented in an input field below it with random data coming from the backend.
