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

## Part 1
```python
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
```python
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](https://github.com/q-viper/Adevent-Of-Code/tree/master/2021) as Jupyter Notebook.
