宁以pass-by-reference-to-const 替换 pass-by-value (前者通常更高效、避免切割问题(slicing problem),但不适用于内置类型、STL迭代器、函数对象) 必须返回对象时,别妄想返回其 reference(绝不返回 pointer 或 reference 指向一个 local stack 对象,或返回 reference 指向一个 heap-allocated 对象,或返回 pointer ...

run a vector search. There are many poor tradeoffs for this such as speed, accuracy, filtering, and heap sorting. These so-called dual systems suffer because the vector databases often don’t have the same (or any) filtering capabilities so they return massive amounts of information that’s...
But there is still another major problem with STL-stringstream: It has no clear() or truncate() method, at least in VC2005. So it grows to infinite, if you use it repeatedly. Deadly for long-running applications. There are two workarounds, if you are dealing properly with internals of...

While sorting randomly ordered data is a well-studied problem which has produced a plethora of useful results over the last five decades such as Quicksort, Merge Sort, and Heap Sort (see [9] for a summary), the importance of sorting almost sorted data quickly has just emerged over the ...
C.tree D.graph 概念题 To build a heap from N records, the best time complexity is: A.O(logN) B.O(N) C.O(NlogN) D.O(N^2) Heapify 从最后一个非叶子节点一直到根结点进行堆化的调整。如果当前节点小于某个自己的孩子节点(大根堆中),那么当前节点和这个孩子交换。Heapify是一种类似下沉的操作...
