Problem Description

As the 2010 World Expo hosted by Shanghai is coming, CC
is very honorable to be a volunteer of such an international pageant. His job is
to guide the foreign visitors. Although he has a strong desire to be an
excellent volunteer, the lack of English makes him annoyed for a long time.

Some countries’ names look so similar that he can’t distinguish them. Such
as: Albania and Algeria. If two countries’ names have the same length and there
are more than 2 same letters in the same position of each word, CC cannot
distinguish them. For example: Albania and AlgerIa have the same length 7, and
their first, second, sixth and seventh letters are same. So CC can’t distinguish
them.
Now he has received a name list of countries, please tell him how many
words he cannot distinguish. Note that comparisons between letters are
case-insensitive.

Input

There are multiple test cases.
Each case begins with
an integer n (0 < n < 100) indicating the number of countries in the
list.
The next n lines each contain a country’s name consisted by ‘a’ ~ ‘z’
or ‘A’ ~ ‘Z’.
Length of each word will not exceed 20.
You can assume that
no name will show up twice in the list.

Output

For each case, output the number of hard names in CC’s
list.

Sample Input

3
Denmark
GERMANY
China
4
Aaaa
aBaa
cBaa
cBad

Sample Output

Problem Description

Like most of the RPG (role play game), “The Magic
Tower” is a game about how a warrior saves the princess.
After killing lots
of monsters, the warrior has climbed up the top of the magic tower. There is a
boss in front of him. The warrior must kill the boss to save the
princess.
Now, the warrior wants you to tell him if he can save the
princess.

Input

There are several test cases.
For each case, the
first line is a character, “W” or “B”, indicating that who begins to attack
first, ”W” for warrior and ”B” for boss. They attack each other in turn.
The
second line contains three integers, W_HP, W_ATK and W_DEF.
(1<=W_HP<=10000, 0<=W_ATK, W_DEF<=65535), indicating warrior’s life
point, attack value and defense value.
The third line contains three
integers, B_HP, B_ATK and B_DEF. (1<=B_HP<=10000, 0<=B_ATK,
B_DEF<=65535), indicating boss’s life point, attack value and defense value.

Note: warrior can make a damage of (W_ATK-B_DEF) to boss if
(W_ATK-B_DEF) bigger than zero, otherwise no damage. Also, boss can make a
damage of (B_ATK-W_DEF) to warrior if (B_ATK-W_DEF) bigger than zero, otherwise
no damage.

Output

For each case, if boss’s HP first turns to be smaller
or equal than zero, please print ”Warrior wins”. Otherwise, please print
“Warrior loses”. If warrior cannot kill the boss forever, please also print
”Warrior loses”.

Sample Input

W
100 1000 900
100 1000 900
B
100 1000 900
100 1000 900

Sample Output

Warrior wins
Warrior loses
