Remember, the recurrence should capture: the number of recursive calls, the size of the subproblems, WebThe key insight in the algorithm is that, for any integers i ≥ μ and k ≥ 0, x i = x i + k λ, where λ is the length of the loop to be found and μ is the index of the first element of the cycle. But it is followed by the following point which I could not understand. in particular, i = k λ ≥ μ, if and only if x i = x 2 i. onupdatefound https://gpstechnologysolutions.com
