What is devising validating and testing of algorithms

Real time Java provides extensions to Java that provide worst-case performance guarantees for various runtime processes (such as garbage collection, class loading, Just-in-time compilation, and thread scheduling).values in ascending order, determines whether a given integer is in the array.You may use only additions and subtractions and a constant amount of extra memory.The running time of your program should be proportional to log : Instead of searching based on powers of two (binary search), use Fibonacci numbers (which also grow exponentially).To estimate how much memory our program uses, we can count up the number of variables and weight them by the number of bytes according to their type.For a To determine the memory usage of an object, we add the amount of memory used by each instance variable to the overhead associated with each object, typically 16 bytes. Padding makes all objects take space that is a mulitple of 8 bytes. Be sure that you computation is consuming enough CPU cycles so that you can measure it accurately. If you are using huge amounts of memory, that could be the bottleneck.

These guarantees are not absolute, but the chance that they are invalid is less than the chance your computer will be struck by lightning.

You may assume all elements in the n-by-n array are distinct.

You are in the middle of a road, but there is a duststorm obscuring your view and orientation.

There is a shelter in only one direction, but you cannot see anything until you are right in front of it.

Devise an algorithm that is guaranteed to find the shelter. Given a arbitrarily long sequence of items from standard input such that one item appears a strict majority of the time, identify the majority item. Maintain one integer counter and one variable to store the current champion item.

We use just a few structural primitives (statements, conditionals, loops, nesting, and method calls) to implement algorithms, so very often the order of growth of the cost is one of just a few functions of the problem size numbers.
