comment Analytical question on year calculation.
@Medex well, it grows to 25 in 6 and tasks each year to double. So to grow half the height must have taken one year because it was half the height and then doubled in one year to reach the full height, so half the height was at 6-1=5 years

comment First order ODE with $f'(x) = 810(10)^x$
@recursiverecursion I found out what $f(x)$ was first and then took the derivative.

comment Analytical question on year calculation.
@Medex I do. I also found an easier way to solve it. The hint is, it doubles in value each year and you need to find how long it took to grow to half the height at 6 years.

comment Degeneracy number of a ring graph
@triomphe yes, i am now confused too. the definition on wiki does not restrict graph size. need to look more into it, i am sorry.

comment Degeneracy number of a ring graph
@triomphe your last formulation is wrong, degeneracy is $$\min\{\max \mathrm{deg}(s) | s \in S\}.$$ This way, tree is 1-degenerate and cycle is 2-degenerate and star is 1-degenerate also. I got confused myself also, sorry.
