PROGRAMMING:Comparison of 2017final complex numbers
Please define a plural class whose real and imaginary numbers are private data members. Define an operator overload function of > (greater than sign) to compare the module size between two complex numbers.
###Input format:
The test input contains several test cases, and each test case occupies one line. Each test case consists of four numbers. The first two numbers represent the real and imaginary parts of the first complex number respectively, and the third and fourth numbers represent the real and imaginary parts of the second complex number respectively. Space between each number. When a test case read in is 0, the input is finished and the corresponding result is not output.
###Output format:
Output one line for each test case. When the modulus of the first complex is greater than that of the second complex, true is output; when the modulus of the first complex is less than or equal to that of the second complex, false is output.
###Input example:
```in
4 6 4 0
1 3 4 1
0 0 0 0
```
###Output example:
```out
true
false
```
