This is a creation in Article, where the information may have evolved or changed. Everyone knows that the single-process nonblocking model of node. JS is suitable for task-intensive (I/O) rather than computational-intensive. So how does it fit into the calculation? Let's do a simple test.

to participate in the next round of comparisons. From this point on, element 8 only needs to be compared with the other winning non-parent nodes just by building the tree structure, for example, only in comparison with 7,9, we can get the minimum element is 7 Then the leaf node of element 7 is changed to ∞, the sibling node 12 and 8, 9 nodes, you can get 8: And so on, finally get the last element 35: Complexity of TimeBecause each time only needs to compare with the other winning n
