All submissions for this problem are available.###  Read problems statements in [Mandarin Chinese](http://www.codechef.com/download/translated/NOV14/mandarin/SEAPERM2.pdf) and [Russian](http://www.codechef.com/download/translated/NOV14/russian/SEAPERM2.pdf).

Sereja have permutation **p\[1\], p\[2\], ..., p\[n\]**. Sereja have made **n** permutations **q\[1\], q\[2\], ..., q\[n\]**, **q\[i\]** is permutation **p** without element **i** (we subtract 1 from all elements bigger than **i**). For example **8 1 2 3 4 5 6 7** without **5** is **7 1 2 3 4 5 6**. Sereja have made random shuffle of **q**. Help Sereja find initial permutation **p**.

### Input

First line contain number of test cases **T**. **T** tests follow. First line of each test case contain number **n**. Next **n** lines describe permutations **q\[1\]**, **q\[2\]**, ..., **q\[n\]**. Each line contain **n-1** number. It is guarantied that there is at least one solution for each test case.

### Output

For each test output permutation **p**. If there is more than one solution - output any.

### Constraints

- **1** ≤ **T** ≤  **10**
- **3** ≤ **n** ≤  **300**

### Subtasks

- Subtask #1: **3** ≤ **n** ≤  **6**  (13 points)
- Subtask #2: **3** ≤ **n** ≤  **50**  (27 points)
- Subtask #3: **3** ≤ **n** ≤  **300**  (60 points)
