HW:
Ms. Mae bought an intelligent robot who can clone himself. But the robot needs a whole month to study the manual, and then work for another whole month to create a clone. After this, he can create a clone every month. Luckily, the newly created clone can clone himself as well. Just as the robot, a clone needs a month to study and another month to create a new clone. If Ms. Mae bought the robot on Jan 1, 2020 and the robot started working right away, how many robots will she have on February 1? March 1? April 1? May 1? on New Year's Day 2021? Do you see anything familiar?
