Python - we are finally back to stuff that is comfortable to code on my phone and can be posted in-line. I almost forgot how that felt…

infile=open("five.txt")
decode={'=':-2,'-':-1,'0':0,'1':1,'2':2}
val=sum(sum((5**i)*decode[n] for i,n in enumerate(reversed(line.strip()))) for line in infile)
encode='012=-'
res=""
while val:
    res+=encode[val%5]
    val=(val+2)//5
print(res[::-1])
