A little rittle = 6

A story of glory = 6

History of the world = 7

Just a fairy tail = 5

Foo = 1

Riddle a little = 8

Have fun = 3

:) = 1

I will provide hints later = 11

End = 3

Hint I = 1

I AM YOU = 0

i am you = 0

Hint II = 1

Palindromes are cool = 11

Hint III = 1

Hint I: BIG = small = 6

Meaning: small -> BIG = 9

Hint IV = 1

Mirrors are also cool = 10

The number indicates

the number of letters that are not symmetric about the vertical axis. All lowercase letters are transformed to uppercase (as indicated in Hint III).

For example:

A little rittle is being transformed to A LITTLE RITTLE

The letters that change when being mirrored are L, L, E, R, L and E - a total of 6 letters.

This works except for the last line (I didn't check all though, is there some more?) :(

Step 1:

Convert all characters into ASCII values.

Step 2:

Declare a variable, say ct=0.

Step 3:

Go through the string. If the ASCII value is even, increment ct by 1

Step 4:

The RHS is the ct
