Given a string, convert the small alphabets of the string to capital alphabets and vice-versa.

Input :

First line of input is number of testcases T.
Then T testcases follow. Each testcase consists of a string of length L.

Output :

For each testcase, output the required string in a new line.

Constraints :

T<15
L<30
Input string consists of letters A-Z and a-z only.

Sample Input :

3
a
A
aA

Sample Output :

A
a
Aa

Score :

C : Total number of non-whitespace characters
L : Number of loops (for, do, while)
I : Number of if, else, ternary(?), goto, switch

T = 10000/(C + 500*L + 300*I)
