at line 50, error 'the operator < is undefined for the argument type(s) boolean, int' occurs.
When I wrote 'if(dist(circles[i].x, circles[i].y, circles[j].x, circles[j].y) < maxDistance){' at that line, the sketch worked.
In case of ' if((dist(circles[i].x, circles[i].y, circles[j].x, circles[j].y) > minDistance) & (dist(circles[i].x, circles[i].y, circles[j].x, circles[j].y) < maxDistance) < maxDistance){', it still does not work.
Is there anything I'm missing?
