Write the formulas

Five flowers are listed with their sepals, petals, stamens and carpels, and whether the carpels are joined. You will write the symbol for a gynoecium, build the formula of every flower, and find the flowers with many stamens.

The idea. Joined carpels go in brackets, such as G(2). Free carpels are written G2. A single carpel cannot be joined, so it is written G1.

Your tasks.

1. Complete gynoecium(g, joined) so that it returns the symbol of the gynoecium.
2. Fill the dictionary formulas with each flower and its formula, such as K4 C4 A6 G(2).
3. Set crowded to a list of the flowers whose stamens are at least twice as many as the petals.
