**Problem F**

**Love Calculator **

**Input:** standard input

**Output:** standard output

**Time Limit:** 2 seconds

**Background**

One day I asked Saima that how much
she loves me. Her answer was "71.43 %". I was surprised as well as
shocked by her answer. I could not understand why she didn't tell 100% and why
she told a particular and peculiar fraction like 71.43. Looking at my
surprised, shocked and nervous face she burst out laughing and told that she
loves me more than any thing in this universe and it was nothing but a silly
and funny love calculation. Then she described me the calculation. In this
problem you will have to write a program so that any one can calculate love
between any two persons very quickly (of course a very silly game).

**Rules**

You will be given two names. These two names can have white
space or some other non-alphabetical characters like $ @ & % etc. But only
the alphabets from a to z or A to Z will participate in love calculation. Each
alphabet has a particular value. The values are from 1 to 26 in ascending order
of the alphabets. Its like this, a = 1, b = 2, c = 3........ z = 26. Both upper
case and lower case holds the same values. Then make the sum of these numbers
until it comes in one digit.[ For example, consider a name 'bcz'. Here, b = 2,
c = 3 & z = 26. So, the sum is (2+3+26) = 31 = (3+1) = 4.] Then the ratio
of these two numbers in percentage will be the result.

Remember : Result can not be more than 100 % . Take the ratio carefully to avoid this problem.

**Input**

Your input will be two names. Each name holds not more than
25 characters. End of file will indicate the end of input.

**Output**

For each pair of names your program will have to calculate
the love between those two persons and give the result as output. In result two
digits to be displayed after the decimal point. All the results must be in new
lines.

**“Hmm! Even love calculators have floating
point variables!! Strange!!!**

**Should we really try to calculate love? Someone
(or two) may become **

**happy to get a score of 100%. But when one
sees the second and **

**third sample input and the corresponding
output one must **

**think the less the better :-)”**
