对应的函数分别为:binary_search, lower_bound, upper_bound 其内部实现非常精妙,详见侯捷的《STL 源码剖析》。当然思想与上文实现大同小异,但是速度方面有待验证。 此外,C库函数也提供了void* bsearch(const void *key, const void *base, size_t n, size_t size, int (*com) (const void *first, const...

If you attempt to pass a C++ function pointer to tsearch(), the compiler will flag it as an error. You can pass a C or C++ function to tsearch() by declaring it as extern "C". Returned value If the node is found, tsearch() returns a pointer to it, otherwise it returns a ...
Figure 5. Example trees, where (a) and (b) are valid AVL trees, but (c) and d are not. **Note **Realize that AVL trees are binary search trees, so in addition to maintaining a balance property, an AVL tree must also maintain the binary search tree property. ...
=XMATCH(TAKE(TOCOL(A:A,1),-1),A:A,,-1) shall be fast . As a result, I must continue to use , and therefore function? Wasn't this function intended to be the 'successor' toMATCH, for which I would read 'able to mimic all that parameter of -1 for XMATCH i...
Later in [53], Jauregui found by means of an exhaustive computer search that there are no more non-equivalent kernels of length 26 that the one found by Golay using a “by hand technique”. More recently, Borwein and Fergurson reported the existence of the Golay kernel of length 20 [54]...
