C++-Programm zum Ermitteln der Maximalsumme eines minimal zusammenhängenden Diagramms

N := 100
Define arrays seq and res of size N.
Define an array tp of size N.
ans := 0
Define a function dfs(), this will take p, q,
   res[p] := seq[c]
   if p is not equal to 0, then:
      ans := ans + seq[c]
   (decrease c by 1)
   for each value x in tp[p], do:
      if x is not equal to q, then:
         dfs(x, p)
for initialize i := 0, when i + 1 < n, update (increase i by 1), do:
   tmp := first value of edges[i]- 1
   temp := second value of edges[i] - 1
   insert temp at the end of tp[tmp]
   insert tmp at the end of tp[temp]
for initialize i := 0, when i < n, update (increase i by 1), do:
   seq[i] := vertexValues[i]
c := n - 1
sort the array seq
dfs(0, 0)
print(ans)
for initialize i := n - 1, when i >= 0, update (decrease i by 1), do:
   print(res[i])
