Today in math class, you were looking at the intersection of two lines. However, after some misbehaviour, your teacher assigned $$T$$ problems for you to solve. All of the problems were of the form: Find the number of intersections between $$d_1$$ and $$d_2$$, where $$d_1$$ is the line with the equation $$y = ax + b$$ and $$d_2$$ is the line with the equation $$y = cx + d$$.

Instead of manually solving the problems like a noob, you plan to use your newly found programming skills from ICS to solve all the problems for you.

#### Constraints

$$1 \le T \le 100$$

$$1 \le a, b, c, d \le 5$$

#### Input Specification

The first line contains an integer $$T$$, the number of test cases.

The next $$T$$ lines contain four integers, $$a$$, $$b$$, $$c$$, $$d$$ describing one test case.

#### Output Specification

For each test case, output the number of intersections between $$d_1$$ and $$d_2$$ on a separate line. If there are an infinite number of intersections then output INFINITE.

#### Sample Input

3
3 2 3 3
1 4 1 4
1 4 4 1

#### Sample Output

0
INFINITE
