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:
for _ in range(int(input())):
    s=input().strip()
    n=len(s)
    def isok(a,b):
        x=len(a)
        y=len(b)
        i=0 
        j=0
        while i<x and j<y:
            if a[i]==b[j]:
                i+=1 
                j+=1 
            else:
                j+=1 
        return i==x
    n*=2 
    ans=["0"*n ,"1"*n ,"01"*(n//2),"10"*(n//2)]
    period=[1,1,2,2]
    #period=10000000000
    mini=1000 
    res=""
    ind=0 
    for i in ans:
        if isok(s,i):
            #print('hi')
            if period[ind]<mini:
                mini=period[ind]
                res=i
        ind+=1 
    print(res)
