In order to illustrate the generality of their main result (Theorem 3.2) with respect to older related results (Nadler’s, Berinde–Berinde, Mizoguchi–Takahashi and Du’s fixed point theorem), the authors presented two examples, i.e., Examples 3.3 and 3.4.
The main aim of this note is to show that Example 3.3 fails in proving the generality of Theorem 3.2 over Berinde–Berinde’s fixed point theorem.
