You are given 2 eggs.
You have access to a 100-storey building.
Eggs can be very hard or very fragile means it may break if dropped from the first floor or may not even break if dropped from 100th floor, Both eggs are identical.
You need to figure out the highest floor of a 100-storey building an egg can be dropped without breaking.

Your job is to measure 45 minutes if you have only two cords and matches to light the cords.

2. Each cord burns from end to end in exactly one hour.

Describe your way of measuring the 45 minutes.
