Transcribed Image Text:Code in Haskell Programming only
Space X is planning to start Star link. Programmers at SpaceX
are having trouble to implement wildcard pattern matching
supporting only the wildcard '?'. The wildcard character '?' can
be substituted by any single lower case English letter for
matching. He has two strings X and Y of equal length, made up
of lower case letters and the character '?'. He wants to know
whether the strings X and Y can be matched or not.
The first line of input contain an integer T denoting the number
of test cases. Each test case consists of two lines, the first line
contains the string X and the second contains the string Y.
For each test case, output a single line with the word Elon if the
strings can be matched, otherwise output Musk.
Input:
Output:
2
Elon
s?or?
Musk
