WebOct 26, 2024 · If you mean a binary heap (that is the implementation with an array) you can walk around the elements and get constant time. If however you consider min-heap as an abstract data structure (no implementation in mind) then you only have access to the extract-min operation and have logaritmic complexity. $\endgroup$ WebSep 27, 2016 · Sorting an array has a very high time complexity; heap operations are so cheap that they are actually used for a decent sorting implementation. Using a heap to find the smallest element is definitely a lot faster than sorting an array.
