Detect circles

The program should count the number of red and black circles on a green background.

In the picture, in addition to circles, there may be rectangles with sides parallel to the borders of the picture.

Tip	We can assume that all figures are separated from each other and from the border

How-to

To run the program on unix-like systems just type:

./gradlew -q run

For windows:

.\gradlew.bat -q run
