I didn't reached the interview round but I can tell the problem they asked in technical round, they asked us to make a dynamic program where there are any number of bikes of your choise and there should be same number of laps also in first round all bikes will be there but in the following bikes the slowest bike will be eliminated, speed of bikes is fixed in all the laps and we have to print the output for bikes like Lap 1 bike 1 distance 0.5 speed 60 total 0.5 And soo on here dist will get double in every round and total dist will be the dist covered by all the bikes in all the laps say 1st bike covered 0.5 next will also cover 0.5 then total 1km and dist will be same for all the bikes in a particular lap
