Until recently, it was not known whether it was possible to stably sort (Le. keeping equal elements in their initial order) an array of n elements using only O(n) data movements and O(1) extra space. In [10], an
sort()在数据小于16的时候采用插入排序,大于16且划分均匀(靠一个划分元素数目的定值判断)时采用快速排序,在划分不均匀的时候采用堆排序。 stable_sort()为了保证数据有序性采用归并排序,归并排序利用inplace_merge实现(一个序列的前一部分和后一部分分别有序,然后将其整个排序)而inplace_merge又分两种情况,有缓冲区...

stably partitions data in O(n) time using O(log n) space, hence the name, which many already consider to be in-place despite not being the optimal O(1). Unlike well-known in-place stable sorts which are O(n log² n), such as std::stable_sort, Logsort is asymptotically optimal....

There is currently no clear consensus on what constitutes as an in-place sort, it boils down to what someone considers a small enough memory footprint to be considered negligable. This typically ranges from the size of a cache line to the size of the L1 cache. ...
order and everything is changed in a stable way, which means that for a fixed value our changes preserved order among elements within that value. Moreover everything needs to be done inplace, that means we can use at most constant additional memory. Whole algorithms has to run in ...
stable_sort(nums.begin(), nums.end(), [](constint& x,constint& y){return(x && !y);}); } }; 这个思路 93.96% beat rate stable_sort的第一个参数是起始位置,第二个参数是终止位置,第三个参数则是一个判断。 比如说后面return的如果是x>y,那么这个数组会变成从大到小排序的数组;在这题中,...
This 'naturally' supplies a sorted _copy_, but if the input-sequence is a list we can just assign to its "include everything" slice to get in-place effect. This recipe specifically demonstrates using this to achieve a stable sort (where items that compare equal keep the same relative orde...
