The Fibonacci recursion tree demonstrates repeated computation by showing that the same subproblems are solved multiple times. For example, when computing the fifth Fibonacci number, the tree contains duplicated subcalls such as fib(2) and fib(3).
Conditions: The problem is being solved recursively.; The recursive decomposition revisits the same subproblem multiple times.
