My implementation of binary heap. Hot Network Questions Expected value exponential inequality non-negative random variable WebThis helps us to efficiently implement one sorting algorithm called heap sort and a priority queue. A binary heap can be efficiently implemented using an array (static or dynamic). To implement a binary heap of height h, we need O(2 h) memory blocks and we insert the items in the array following level-order (breadth first) of a tree. Figure 2 ...
WebAug 28, 2015 · For bottom up, you consider the array of n elements to be n groups of size 1. You merge even and odd groups from one array to the other, with the direction alternating each time you complete a pass. WebOct 21, 2014 · I wrote some C code to analyze the number of comparisons and runtime of building a heap and running heapsort. However, I'm not sure if the output of my code makes sense. Heapsort should perform at O (n log n), but the number of comparisons I'm seeing doesn't seem to be very close to that. For example, for an input of size n = 100, I'm …
WebIf you want to sort only the first 5 elements of the array, simply pass x instead of n (i.e., 5). The routine does not care whether a few more spare elements are lying behind the ones you use. That said, yes, follow DXZ's … WebMar 24, 2024 · I am trying to count the number of comparisons done by heap sorting algorithm. my code is based on priority queue and I want to know where I should put the counter. here is what I have but when I try to print the counter it shows zero counts, what am I doing wrong?
