Failing Two Test Cases
it is the same solution as yours, just one change, sort according to the end of their diameters, not the start

Then simpy remove the circle that comes second and is overlapping
the code i have pasted, i have submitted on hackerblocks and works perfectly,
if your doubt is solved, please mark it as resolved
