WebApr 13, 2024 · The time and space complexity of the priority queue in C++ depend on the implementation of the underlying data structure, which is typically a binary heap. The binary heap is a complete binary tree where the parent node is either greater than or equal to (for max heap) or less than or equal to (for min heap) its children. WebTime complexity is where we compute the time needed to execute the algorithm. Using Min heap First initialize the key values of the root (we take vertex A here) as (0,N) and key values of other vertices as (∞, N). Initially, our problem looks as follows: This initialization takes time O (V).

WebA max heap is a range of elements [f, l) that has the following properties: With N = l - f, for all 0 < i < N, f [ (i - 1) / 2] does not compare less than f [i] .
