\( f \) is a function whose domain is the set of nonnegative integers and whose range is contained in the set of nonnegative integers. \( f \) satisfies the condition that \( f(f(n)) + f(n) = 2n + 3 \) for all nonnegative integers \( n \). Find \( f(2014) \).

Let's think step by step and output the final answer within \boxed{}.
