WebIn your case sorted means : the second one does not depend of the first one. [3 4 1 2] and [4, 3, 2, 1] are two possible orders. The algorithm suppose transitivity : if x <= y and y <= z then x <= z. In this case it's not true. You can however modify the data : if x depends of y and y depends of z then add z to x' dependency list. WebFeb 20, 2024 · Topological Sorting problem that uses the depth-first search.
