Erasing everything from every element in a list except the first few numbers in those elements


Erasing everything from every element in a list except the first few numbers in those elements

Does that help You do not need regex for this, you can use split within a list comprehension.
code :
>>> l = ['29382 this is something', '2938535 hello there', '392835 dont care for this', '22024811 yup']

>>> [i.split(' ', 1)[0] for i in l]
['29382', '2938535', '392835', '22024811']

this one helps. The erase() code is operating on a copy of the lists, not on the actual lists in the hashmap. This creates a copy:
code :
list<time_t> lista = (*it).second;
list<time_t>& lista = (*it).second;
(*it).second.push_front(fecha);

like below fixes the issue You need to use .append(), .html() will overwrite the contents.
code :
$('#tdJane').append('<input type="hidden" id="hid3" value="newest text">');
 $('#tdJane').append($('<input/>',{type:'hidden',
                                   id: 'hid3',
                                   value:'newest text'}));

wish of those help To make the function signatures compatible, your removeObject must accept a generic pointer and cast it appropriately:
code :
void removeObject(void *vptr) {
    Object *object = (Object *)vptr;
    free(object->ptr);
    free(object);
}
Erasing elements from list in multiple threads

To fix this issue Erasing an element from a list is indeed a "write" operation.
Some next/previous pointers must be changed and one of the nodes will be deallocated. For example, take the list A <-> B <-> C
code :
A->next = C
C->prev = A
delete B->data
delete B
std::string str1 = "Text with some   spaces";
str1.erase(std::remove(str1.begin(), str1.end(), ' '), str1.end());
