There is this seem to basic way of discover in the event that a connected record features a cycle after which go back brand new node that is in the beginning of the duration that’s floy’s algorithm that have slow/fast information. Brand new password plus the logic is clear except step one matter. This new method is dependent on the belief that node inside the new circle that recommendations can meet is strictly the same quantity of actions because from the San Juan, TX women are most attractive head of the list right up until the start of the fresh new loop. One part is what I really don’t get. Anytime Slow and you may Quick both start on direct away from the list, when Slow do k strategies and you may has reached the start of the new loop, Quick gets over 2k strategies which will be efficiently k methods into cycle. So fast try prior to slow by the k methods and at the rear of out-of slow (which is in the beginning of the circle) Letter – k where N ‘s the cycle dimensions. Because at every action timely approaches sluggish and you will timely was trailing sluggish by the N – k nodes, timely tend to reach sluggish in the N – k procedures. So far, sluggish will have complete Letter – k procedures and additionally be from inside the node N – k. Punctual might have over 2(Letter – k) procedures and additionally be on node 2N – 2k + k = 2N – k (due to the fact punctual was at node k). Since this is a loop 2N – k = N – k and hence it meet at node N – k. (suite…)
