Is it possible to initialize a vector and return it at the same time in c++?

So I have a question that involves returning 2 values as a vector on leetcode. What I want to do is after finding these two values, create a new vector with these values and return the vector at the same time. Essentially, turn the lines

vector<int> temp;
temp.push_back(a);
temp.push_back(b);
return temp;

into one line, hopefully something like

return new vector<int>{a,b};

Is it possible to do something like this in C++?

Even more concisely, you can use list initialization.

  1. in a return statement with braced-init-list used as the return expression and list-initialization initializes the returned object
std::vector<int> foo(int a, int b)
{
    return {a, b};
}
