BeforeLWG713, the complexity requirement allowedsort()to be implemented using onlyQuicksort, which may needO(N2)O(N2)comparisons in the worst case. Introsortcan handle all cases withO(N⋅log(N))O(N⋅log(N))comparisons (without incurring additional overhead in the average case), and...
I've run it multiple times and the stable_sort solution always manages to squeeze right under the time limit. Also the complexity is nmlog(nm) →Reply brdy 7 years ago,#| 0 Auto comment: topic has been updated bybrdy(previous revision,new revision,compare). ...
The complexity (efficiency) of common operations on vectors is as follows: Random access - constant𝓞(1). Insertion or removal of elements at the end - amortized constant𝓞(1). Insertion or removal of elements - linear in the distance to the end of the vector𝓞(n). ...
总之,std::list<>::sort()函数本身是不稳定的,但是在特定的场景下可以使用std::stable_sort()函数来实现稳定的排序。同时,在使用std::list<>::sort()函数之前,需要注意它可能会导致迭代器失效的问题。 相关搜索: 当std::sort变得不稳定时? std::sort 数组 linux sort 稳定排序 指向成员函数的指针 ...
