 yes, the first algorithm I have proposed is a very dumb version of the
 _Bellman-Ford_ algorithm, it's dumb, because it loops :wink: After our “looping”
 prevention we got to the point that is almost the _Bellman-Ford_ with the one

 2. our naïve approach with the fixed count of iterations instead of the
    `do-while` loop results in the same worst-case time complexity:
    $$
-   \mathcal{O}(\vert V \vert \cdot \vert E \vert)
+   \Theta(\vert V \vert \cdot \vert E \vert)
    $$
 
 3. and finally the well-known Bellman-Ford's algorithm time complexity:
    $$
-   \mathcal{O}(\vert V \vert \cdot \vert E \vert)
+   \Theta(\vert V \vert \cdot \vert E \vert)
