Some of Thore’s pink buttons. Photographer: Thore Husfeldt.
Thore is a fashionable man. Every time he meets up with
his programming team, he wears his hot pink team hoodie over a
salmon colored shirt with shirt buttons in a dashing rose or
pink shade. Of course, he can’t show up to two training
sessions with the same buttons on his shirt, that would cause
unbearable ridicule. If he can’t find buttons for this perfect
color combination, he will come up with some poor excuse for
not showing up. He has a box full of different colored buttons
in labeled packages. Unfortunately, Thore is color blind, so
his helpful daughter has labeled each package with the color of
the buttons. Her writing is terrible though, she mixes
uppercase and lowercase arbitrarily and has no spacing between
words, so Thore needs your help to decipher the names on the
labels and select buttons with either “pink
” or “rose
somewhere in the name, ignoring case.
Input starts with an integer $1 \leq N \leq 1\, 000$, the number of
button packages in the box. The following $N$ lines each has a color name, one
for each package. The names consist of up to 30 characters of
letters A - Z, a - z.
Print one integer, the number of training sessions Thore can
attend. If he can’t attend any session because there are no
pink buttons, output his standard excuse “I must watch Star Wars with my daughter”.
