supports O(1) prepend, and
that I can call bisect.bisect_left on, which means the list must be sorted.
Prepending to a list via list.insert(0, item) is O(N); however, O(1) prepend can be emulated by maintaining the list in reverse order in w...

{
int amount = std::strtol(argv[1], 0, 10);
int test[amount];
for (int i = 0; i < amount; i++)
{
test[i] = i;

I have a function that makes async calls:
bindSemantic() {
const unom = this.form.get('unom').value;
const { user } = this.data.map.userInformation;
this.loading$.next(true);
this.loadAddressingObject(unom).subscribe(
(response) => {
this.addressingObjectListM...
