• Day 1.1: calculate total fuel required for all modules of space craft based on mass
• Day 1.2: extend Day 1.1 to include fuel for fuel (and so on)
• Day 2.1: create Intcode program
• Day 2.2: find pair producing output of 19690720
• Day 3.1: fix fuel management system: determine Manhattan distance from central port to closest intersection
