Suppose your engine has lost power and you need to jump start the engine by supplying a bolt of power to it. You have a battery that can supply bolts of power at integer power levels (e.g. 1W, 2W, 3W, 4W, ...). As soon as you supply a bolt of power strong enough (say nW), the engine will turn on. As long as you supply a bolt of power exceeding nW, the engine will turn on. However, you don't know what n, the minimum power, is. Therefore, you can simply try 1W, then 2W, then 3W and so on, until the engine turns on. With this method, the total amount of power supplied, including all the tries, would be: 1+2 +3 + ... +n= ©(n²) Design an algorithm that will successfully turn on the engine, but which uses only ©(n)W total power. Show that your algorithm uses O(n)W power.
