Dynamic arrays and amortized analysis answers

WebSep 4, 2024 · Dynamic Arrays and Amortized Analysis. In this module, we discuss Dynamic Arrays: a way of using arrays when it is unknown ahead-of-time how many elements will be needed. Here, we also discuss amortized analysis: a method of determining the amortized cost of an operation over a sequence of operations. … 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! But appends take time only when we insert into a full array. And that's pretty rare, especially if we double the size of the array every time we run out of space.

Now suppose that we want to calculate amortized cost c ^ i when first r > 0 bits are 1. Thus, c ^ i = 2 r + 1 − 2 + ( 0 − ( 2 r + 1 − 2)) = 0. If r = 0 then c ^ i = 3.
