quicksort(array[:i-1]) doesn't actually call quicksort on the first partition of the array, it calls quicksort on a copy of the first partition of the array. Thus, your code is partitioning the array in place, then creating copies of the halves and trying to sort them (but never do...

Instead of using recursion, the idea is to use a stack to store subarray’s starting and ending index for later processing. Note that the partitioning logic would remain the same. Practice this algorithm The iterative Quicksort implementation can be seen below in C++, Java, and Python: ...

and, like Quicksort, has excellent performance traditionally, and beyond selecting thek'thelement, it also partially sorts the data. It is also anin-place algorithm, requiring only constant memory overhead if tail-call optimization is available, or we can eliminate the tail recursion with a ...
to the guaranteed O(n log n) heapsort if the recursion depth becomes too big. In pdqsort we adopt a hybrid approach, (deterministically) shuffling some elements to break up patterns when we encounter a "bad" partition. If we encounter too many "bad" partitions we switch to heapsort. ...
sorted(iterable [, cmp] [, cmp=cmpFct] [, key=keyGetter] [, reverse=bool]) [2.4] works like the new in-place list.sort(), but sorts a new list created from the iterable.Notes: (1) if i or j is negative, the index is relative to the end of the string, ie len(s)+i or...
template <typename RanIt> void sort(RanIt first, RanIt last){ // . . . } You can and should sort a std::vector<int> without explicitly specifying that RanIt is std::vector<int>::iterator. When the compiler sees sort(v.begin(), v.end());, it knows what the types of v.begin()...
