You are standing at point on an infinite plane. In one step, you can move from some point to any point *as long as* the Euclidean distance, , between the two points is either or . In other words, each step you take must be exactly or in length.

You are given queries in the form of , , and . For each query, print the minimum number of steps it takes to get from point to point on a new line.

**Input Format**

The first line contains an integer, , denoting the number of queries you must process.

Each of the subsequent lines contains three space-separated integers describing the respective values of , , and for a query.

**Constraints**

**Output Format**

For each query, print the minimum number of steps necessary to get to point on a new line.

**Sample Input 0**

```
3
2 3 1
1 2 0
3 4 11
```

**Sample Output 0**

```
2
0
3
```

**Explanation 0**

We perform the following queries:

- One optimal possible path requires two steps of length : . Thus, we print the number of steps, , on a new line.
- The starting and destination points are both , so we needn't take any steps. Thus, we print on a new line.
- One optimal possible path requires two steps of length and one step of length : . Thus, we print on a new line.
