Overlapping subproblems occur when the same smaller problem is solved multiple times during a recursive process. The Fibonacci tree makes this concrete by showing repeated calls such as fib(2) and fib(3), which cause redundant computation.
Conditions: The problem can be solved recursively.; The same subproblems appear multiple times in the recursion tree.
