Python has never been as speedy as C or Java, but several projects are in the works to get the lead out of the language.
The following example shows the usage of std::list::push_front() function.Open Compiler #include <iostream> #include <list> using namespace std; int main(void) { list<int> l; for (int i = 0; i < 5; ++i) l.push_front(i + 1); cout << "List contains following elements" <<...
