Big O notation is used in Computer Science to describe the performance or complexity of an algorithm. Big O specifically describes the worst-case scenario, and can be used to describe the execution time required or the space used (e.g. in memory or on disk) by an algorithm.
I need to implement and test an algorithm with a 2^n complexity. I have been trying to find one for a while. If there is any way I can acheive this by implementation -- with a exact complexity of 2^n that would be optimal. If anyone knows of a location I can find an example, or could help me implement one, that would be awesome :-). The basic operation can be anything, but a single statment like i++; would be best.
Can you imagine our world without drinking water?We use water every day for cooking and washing.We use water without even thinking that there are places where people have no clear water to drink.However,there are water shortages all over the world.We need water not only for our homes,gardens and factories.We need water to survive as a species.Water pollution is one of the burning problems of modern society.Plants and factories pour chemicals into the lakes and rivers.Contaminated water goes to the seas and oceans.We must take measures before it is too late.First of all,we can save water at our homes.We should take showers instead of baths.We should repair the taps and pipes in our houses to avoid leaking.Factories and plants should use recycled water to stop polluting rivers and lakes.It's extremely important to persuade people to save water.People must understand that maintaining clean and healthy environment is in their own best interests.Too much depends on our decisions and our actions.We must do everything we can before the world without water has become a horrible reality.
