PROGRAMMING:Inside and outside the circle

Small c learning English very hard, but the learning method is wrong, English achievement is not up and down, the result slowly lost interest in English, anyway, or went to a local high school, became a high school student. As a science student, small C's mathematics and chemistry is quite good, so there are often girls to ask questions. Today, the math teacher talked about the elliptic equation x ^ 2 / A ^ 2 + y ^ 2 / b ^ 2 = 1 (a, b > 0). The math teacher asked, if you know the elliptic equation and a, B, give a point (x, y), judge the position of the point relative to the ellipse. Little c laughs when he hears this question. He knows that as long as he substitutes the point coordinates into the equation, the result on the left is greater than 1, which is outside the ellipse, and less than 1 is inside the ellipse.
###Input format:
Multiple sets of test data, each test number given a B x y, 4 integers（ 1<=a,b,x,y<=100)
###Output format:
Output "out ellipse" and "in Ellipse" according to the relative position（ There is no ellipse in the data (this is the case) and each output takes one line.
###Input example:
Here is a set of inputs. For example:
```in
1 2 2 2
1 2 0 0
```
###Output example:
The corresponding output is given here. For example:
```out
out ellipse
in ellipse
```
