There is a building with 100 floors (can be any positive integer). You have 2 light bulbs. They are special type of bulbs and you have only 2 of them. The specialty of the bulb is that they don’t break easily when dropped from a height. The idea is to find the minimum floor of the building from which the bulb would break. You need to suggest a solution which will take the least number of iterations (for the worst case scenario) to find the minimum floor from which the bulb breaks. Remember that the answer should be mathematically proven to give the minimum iterations. Also note that once you throw a bulb and it doesn’t break, you can automatically recall the bulb without going down the building to fetch it.

250.250.250.250 - 256.256.256.256 -> cable, FranceWhich indicates all ip addresses between 10.10.10.10 to 20.20.20.20 are of type ‘cable’ and belong to the country USA, similarly with other ip address set.
Question:

Arrange this data into a data structure in such a way that given an ip address (e.g. 21.21.21.21) retrieve the type of service (cable, DSL.. ) and country (USA, Getrmany..) in the fastest possible way.Note: the number of such ip address sets could be very large. Also for every ip address between the start(10.10.10.10) and end (256.256.256.256) there is a type and country associated.
