comment A contest question on probability
a contest Q can't be this vague. your Q fuzzy even in the basic terminology-- "..the set (d1,,,dk) contains..". you mistook the Q or something else missing.

comment A contest question on probability
The definition of nice integers reads like the following and nothing else: $d_5$ has to be 6-- since it's the only digit greater than 5. When $d_5=6$, $d_4=5$, .., $d_1=2$. And the only nice integer is 234561. something missing here.

comment Graph Verification Problem
if the two arguments of $f$ are two partitions and not just any two subsets of $V$, you can't verify the edge set for all cases: think about a clique with one edge missing.
