// Task 2 ???

// Your task is to translate a message in some alien language (let's call it Alienski).

// The message could be created by following simple rules and from two known languages, English and Spanish.

// Each word in Alienski is constructed by subtracting the letters from English and Spanish (absolute value) and that is the resulting letter.

// There are two special cases. If in each of the words the symbol is '-' (hyphen) or ' ' (space) it is mandatory for it to be kept this way.

// There won't be a case with a '-' (hyphen) and a ' ' (space) at the same time.

// If one of the words is with more letters than the other just add the letters from the longer word to the result.

// Example:
// Copy
// talk
// hablar
// Copy
// a b c d....
// 0 1 2 3....
// t - h = | 19 - 7 | = 12 = m
// a - a = | 0 - 0 | = 0 = a
// l - b = | 11 - 1 | = 10 = k
// k - l = | 10 - 11 | = 1 = b
// empty - a = a
// empty - r = r

// Result:

// makbar
// Input:
// Read from the standard input:

// Two lines with messages in English and Spanish
// Each message is on new line.
// Output:
// Print on the standard output:

// On the single line of the output, print the decoded message in Alienski
// Constraints:
// All the letters will be small letters from the Latin alphabet and the special symbols '-' (hyphen) and ' ' (space).
// Hint
// Use the ASCII table
// 'a' - 'a' = 0
// Sample tests:
// Input
// Copy
// thank you
// muchas gracias
// Output
// Copy
// hncgk  idacias
// Note: There are two spaces here

// Input:
// Copy
// test
// el examen
// Output
// Copy
// ph pxamen
