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. There should only be one method with the following signature: void countUp(int start, int end) { // All code exercise code should go here } Here is example output with start=0 and end=5: 0 1 2 3 4 5
