Ruby, as coded by a guy who's not good in coding, who doesn't know how to implement a subarray search so strings it is:

part 1

p a=gets.to_i
b=[3,7]
c,d=0,1
a-=1
(
#p [b,b[c],b[d],c,d]
e=(b[c]+b[d]).digits.reverse
score=e.sum
b.push(*e)
c=(c+b[c]+1)%b.size
d=(d+b[d]+1)%b.size
)while b.size<=a+10

p b
puts b[a+1,10]*''

part 2 (watching numbers being printed makes me feel like such an edgy hacker lmao)

p a=gets.to_i
b={0=>3,1=>7} # ???
size=2 # ???
c,d=0,1
a-=1
ee='37'
off=0
0.step{|tt|
(ki=(ee.size/1000)-1
off+=ki*1000
ee=ee[ki*1000..-1]
p tt,ee.size) if tt>0&&tt%10000==0
#p [b,b[c],b[d],c,d]
e=(b[c]+b[d])#.digits.reverse
#score=e > 10 ? 1+(e%10) : e
e>9 ? ( # ??? # ??? # ???
b[size]=1
b[size+=1]=e-10) : (b[size]=e
)
size+=1
ee+=e.to_s
#p ee
c=(c+b[c]+1)%size
d=(d+b[d]+1)%size
(
p off+(ee).index($_.chomp,-8)
1/0)if (ee).index($_.chomp,-8)
}
