WebInsert: $\mathcal{O}(\log n)$ Get-Min: $\mathcal{O}(1)$ Extract-Min: $\mathcal{O}(1)$ Amortized Time. Simple implementations of a priority queue (e.g. any balanced BST, or the standard binary min-heap) can achieve these (amortized) running times by simply charging the cost of Extract-Min to insert, and maintaining a pointer to the minimum element. http://duoduokou.com/cplusplus/26922690293536707081.html
