Exercise #1: A robot lands on Mars, which happens to be a cartesian grid; assuming that we hand the robot these instructions, such as LFFFRFFFRRFFF, where "L" is a "turn 90 degrees left", "R" is a "turn 90 degrees right", and "F" is "go forward one space, please write control code for the robot such that it ends up at the appropriate-and-correct destination, and include unit tests. Here is an example output with command "FF": [0, 2] Exercise #2: Part 1: Write a program that counts in sequential order when given a start and end value - without using any iterative programing loops, i.e. while, for, do, for-each, etc. You can assume that both the start and end values will always be positive and that the start value will always be less then the end value.
