Advent of Code 2021 Python Solution: Day 2

Again, I will be using my helper function created on day 1 and the input data will be in same format.

Part 1

hs = 0 vs = 0 for d in data: k,v = d.split() if k =="forward": hs+=int(v) elif k == "down": vs+=int(v) elif k=="up": vs-=int(v) print(hs*vs) 

Answer of test data will be 150 and of real input will be 1947824, we just have to give data1 instead of data in loop.

Part 2

hs = 0 vs = 0 aim = 0 for d in data1: k,v = d.split() v = int(v) if k =="forward": hs+=v vs+=aim*v elif k == "down": aim+=v # vs+=v  elif k=="up": aim-=v # vs-=v  print(hs*vs) 

The output of above code will be 1813062561.

All of my codes are available in GitHub as Jupyter Notebook.
