You took a peek on Thanos wearing Infinity Gauntlet. In the Gauntlet there is a place for six Infinity Gems:
Using colors of Gems you saw in the Gauntlet determine the names of absent Gems.
In the first line of input there is one integer n
(0≤n≤6
) — the number of Gems in Infinity Gauntlet.
In next n
lines there are colors of Gems you saw. Words used for colors are: purple, green, blue, orange, red, yellow. It is guaranteed that all the colors are distinct. All colors are given in lowercase English letters.
In the first line output one integer m
(0≤m≤6
) — the number of absent Gems.
Then in m
lines print the names of absent Gems, each on its own line. Words used for names are: Power, Time, Space, Soul, Reality, Mind. Names can be printed in any order. Keep the first letter uppercase, others lowercase.
4
red
purple
yellow
orange
2
Space
Time
0
6
Time
Mind
Soul
Power
Reality
Space
In the first sample Thanos already has Reality, Power, Mind and Soul Gems, so he needs two more: Time and Space.
In the second sample Thanos doesn‘t have any Gems, so he needs all six.
