WebNov 17, 2024 · Floyd's algorithm. The name detect_cycle_constant_time () is a bald-faced lie. The algorithm needs linear time in the number of nodes. Doing an early return would simplify your code. As you don't allocate any resources, there goes the only argument against. Doing data-flow analysis is much more involved. WebFeb 9, 2013 · 2. This algorithm will still take Θ (n) time. To see this, we can show that the algorithm is O (n) and Ω (n). For the O (n) part, note that this algorithm clearly can't be any asymptotically slower than the version in which FixHeap takes O (log n) time each. Since the heapify algorithm takes O (n) time in that second case, we can get an O (n ...
