What is the difference between std::stable_partition() and std::partition()?

help you fix your problem The best way to figure this out is probably with an example. Let me plagiarize the example from cppreference here:
code :
#include <iostream>
#include <algorithm>
#include <vector>

int main()
{
    std::vector<int> v{0, 0, 3, 0, 2, 4, 5, 0, 7};
    std::stable_partition(v.begin(), v.end(), [](int n){return n>0;});
    for (int n : v) {
        std::cout << n << ' ';
    }
    std::cout << '\n';
}

C++ stable_partition Compiler Error

around this issue The problem is that sameBaseReg is a member function of AnalyzeMemOps. You can't use it like an ordinary non-member function because it can only be called on an object.
If you have a modern compiler that supports C++0x, C++ TR1, or if you have Boost handy, you can use bind to bind the pointer to member function to the this object:
code :
std::bind(&AnalyzeMemOps::sameBaseReg, this, std::placeholders::_1)

Equivalent of C++'s stable_partition in clojure?

this one helps. In C++, there is a function in the standard library called stable_partition that takes a collection and a predicate. It divides the collection and puts those elements for which the predicate returns true in one place and those elements for which the predicate returns false in another place, while preserving the relative order of the elements. , The simplest version of this I think is:
code :
(defn stable-partition [p? coll]
  (map (group-by p? coll) [false true]))

What is the difference between dynamic.partition=True and dynamic.partition.mode = nonstrict?

I hope this helps you . Although there is much to google, here is a short answer.
If you want to insert dynamically into Hive partitions both values need to be set and you can then load many partitions in one go:
code :
SET hive.exec.dynamic.partition=true;
SET hive.exec.dynamic.partition.mode=nonstrict

create table tblename (h string,m string,mv double,country string)partitioned by (starttime string) location '/.../...'

INSERT overwrite table tblename PARTITION(starttime) SELECT h,m,mv,country,starttime from tblename2
INSERT into table tblename PARTITION(starttime='2017-08-09') SELECT h,m,mv,country from tblname2 where to_date(starttime)='2017-08-09'

What is the difference between mysql drop partition and truncate partition

it should still fix some issue Both throw the data away. And it is not 'transactional', so you cannot recover the data with a ROLLBACK.
DROP PARTITION also removes the partition from the list of partitions.

stable_partition and getting O(nlogn) swaps

it should still fix some issue Think recursively.
If both left half and right half are stable-partitioned, as in
code :
0...01...10...01...1
     b    m    e
iter stable_partition(begin, end) {
    if (end - begin < 2)
        return;
    iter mid = begin + (end - begin) / 2;
    iter left_break = stable_partition(begin, mid);
    iter right_break = stable_partition(mid, end);
    return rotate(left_break, mid, right_break);
}
