You are a surgeon who has to perform 3 operations today, but you only have 2 pairs of gloves (a and b) to perform the operations. Each of the people you are performing surgery on are infectious so you cannot touch any of them or their bodily fluids and they can't touch each other's bodily fluids. How do you perform all 3 operations with only 2 pairs of gloves?
Operation 1. Put pair a on and put pair b on top of pair a Operation 2. Remove pair b Operation 3. Take pair b and put it over pair a inside out
In series 6,4,1,2,2,8,7,4,2,1,5,3,8,6,2,1,7,1,4,1,3,2,8,7,6, how many pairs of successive numbers have a difference of 1 each?
A doctor wants to operate for three different persons who were wounded. But he had only two surgical gloves. There is not any blood contact between the three persons.
How can he operate for the three people with two pair of surgical gloves?
You have 19 eggs. 18 of them have the same weight and 1 of them is different, but you do not know if it is heavier or lighter than the others.
Using the best possible strategy, in the worst case scenario, how many weighing do we need to perform in order to correctly identify the different egg?
Edit : You do not necessarily need to find if the egg is heavier or lighter than the others.
