WebAmortized analysis of expand Now consider a dynamic array initialized with size 1 and a sequence of m APPEND operations on it. Analyze the amortized cost per operation Assumption: only count array assignments, i.e., append an element and copy an element WebDec 7, 2024 · An amortized analysis of the process gives a complexity of O (n). When the array of capacity N is full, instead of copying the N elements into an array of capacity 2N, they are copied into an array with N/4 additional cells, i.e an array of capacity (N + N/4). Show that performing a sequence of n additions to the array still runs in O (n).
WebDec 12, 2024 · We have a dynamic array with the size of Fibonacci numbers. Assume that F (k) is the array's current size (F (k) is the k-th number of Fibonacci series). We have two rules here: 1)If after inserting an element in the array, the number of array elements is F (k-1), we create a new array with the size of F (k+1) and copy the previous elements to ...
