Dynamic arrays and amortized analysis answers
WebThere are no amortized costs for an array like this. Consider your example 1$ 2$. When adding one element, you will have to increase the size of the array. Now remove one element, and you have to reduce the size. Now again add one element. Etc. Now consider a larger array with n = m. WebDesign a data structure that supports these two operations such that NEWESTNEIGHBOR takes O (1) worst-case time and INSERT takes O (1) amortized time. Note that the length of the array neighbors given to INSERT may vary. (Hint: Use a potential function for the amortized analysis.)

Webof calls to Insert take signi cantly less work, using amortized analysis, we can show that the amortized cost of a single insert is O(1), giving us O(n) amortized cost of inserting n items into a dynamic array. 3.1 Aggregate Analysis Using aggregate analysis, we can look at the cost of each step in Figure 5. As illustrated in Figure 5, WebDoing all that copying takes time, where n is the number of elements in our array. Oof. That's an expensive cost for an append. In a fixed-length array, appends only take time! …
