Answer Posted / shantanu_sanjeev
For the best solution the worst case max drops will be "24"
For this we divide it into
1st five blocks from bottom of size 20 : 5*20 = 100
Next ten blocks of top of size 10 : 10*10 = 100
This will have a worst case at 99 when there will be 24
drops and all other numbers above 99 will have less than 24
drops.
