Problem: Let's say string s has period k if s_i = s_{i + k} for all i from 1 to |s| - k (|s| means length of string s) and k is the minimum positive integer with this property.

Some examples of a period: for s="0101" the period is k=2, for s="0000" the period is k=1, for s="010" the period is k=2, for s="0011" the period is k=4.

You are given string t consisting only of 0's and 1's and you need to find such string s that:

  1. String s consists only of 0's and 1's; 
  2. The length of s doesn't exceed 2 ⋅ |t|; 
  3. String t is a subsequence of string s; 
  4. String s has smallest possible period among all strings that meet conditions 1—3. 



Let us recall that t is a subsequence of s if t can be derived from s by deleting zero or more elements (any) without changing the order of the remaining elements. For example, t="011" is a subsequence of s="10101".

Input

The first line contains single integer T (1 ≤ T ≤ 100) — the number of test cases.

Next T lines contain test cases — one per line. Each line contains string t (1 ≤ |t| ≤ 100) consisting only of 0's and 1's.

Output

Print one string for each test case — string s you needed to find. If there are multiple solutions print any one of them.

Example

Input


4
00
01
111
110


Output


00
01
11111
1010

Note

In the first and second test cases, s = t since it's already one of the optimal solutions. Answers have periods equal to 1 and 2, respectively.

In the third test case, there are shorter optimal solutions, but it's okay since we don't need to minimize the string s. String s has period equal to 1.

Solution (in PYTHON3):

Solution:
numTests = int(input())
for a in range(numTests):
    string = input()
    # n 1s and m 0s in any order,
    # we can clearly alternat in inserting 1s and 0s
    ones = 0
    zeros = 0
    for i in range(len(string)):
        if string[i] == "1":
            ones += 1
        elif string[i] == "0":
            zeros += 1
    if len(string) <= 2:
        print(string)
    elif ones == 0 or zeros == 0:
        print(string)
    else:
        element = "01"
        if string[0] == "1":
            element = "10"
        '''
        curr = int(string[0])
        goal = str(curr)
        for i in range(1, len(string)):
            if int(string[i]) != 1 - curr:
                goal += str(1-curr)
                goal += string[i]
            else:
                goal += string[i]
                curr = 1 - curr
        '''
        element = element * (len(string) - 1)
        if string[-1] != element[-1]:
            element += string[-1]
        print(element)
