Heap leachingHeap and dump leaching of sulphide minerals have become well-established techniques for the processing of low grade ores, especially of copper, over the past 30 years. The oxidative dissolution of sulphides in heaps can be significantly enhanced by microbial colonies, but the ...
再来看看heap.Push是怎么保证插入新元素时,顺序数组仍然是一个最小堆。 // Push pushes the element x onto the heap. The complexity is// O(log(n)) where n = h.Len().funcPush(hInterface,xinterface{}){h.Push(x)up(h,h.Len()-1)} 首先调用h.Push将元素推入用户定义的类型,即前述的PriorityQ...

Green = n/2^1 * 0 (no iterations since no children) red = n/2^2 * 1 (heapify will perform atmost one swap for each red node) blue = n/2^3 * 2 (heapify will perform atmost two swaps for each blue node) purple = n/2^4 * 3 (heapify will perform atmost ...
