# Input Format
#
# The first line contains an integer T (the number of test cases).
# Each line i of the T subsequent lines contain a String S.


# Output Format
#
# For each String S_j (where 0 <= j <= T-1), print S_j's even-indexed characters,
# followed by a space, followed by S_j's odd-indexed characters.
