WebNov 7, 2024 · The 7th smallest element must be in first 7 levels. Total number of nodes in any Binary Heap in first 7 levels is at most 1 + 2 + 4 + 8 + 16 + 32 + 64 which is a constant. Therefore we can always find 7th smallest element in time. If Min-Heap is allowed to have duplicates, then time complexity becomes Θ(Log n). 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).
