Problem: Solve the mystery.  
Input:
String which consists of words(all the characters of any word are lower case letters) and punctuation marks(consists of {'.' , ',' , '?' , '!'}). Also every input string consists of one '*' in it.
It is guaranteed that strings doesn't start or end with space(' ') and only one answer exists for each case.  

Output:
Lower case letter.  

Constrains:
1 ≤ t ≤ 1000
2 ≤ length of string(n) ≤ 100

Solution (in PYTHON):

Solution:
t = int(raw_input())
for qq in xrange(t):
    ss = raw_input()
    s=''
    for char in ss:
        if char.isalpha() or char=='*':
            s+=char
    i=0
    j=len(s)-1
    while i<=j:
        if s[i]==s[j]:
            i+=1
            j-=1
            continue
        else:
            if s[i]=='*':
                ans=s[j]
            else:
                ans=s[i]
            break
    print ans
