What prevents a large company with deep pockets from rebranding my MIT project and killing me off? with seed values . Fibonacci series is the sum of two preceding ones. Binary search takes four arguments and accesses array elements stored in memory. Solutions can be iterative or recursive (though recursive solutions are generally considered too slow and are mostly used as an exercise in recursion).
