'how to set filter from another view?
std::vector v1 {4,2,7,6,4,1};
std::vector v2 {3,0,0,0,0,3};
I want to get the values in v1 with the condition v2=3
my desired result [4,1]
I tried with filter but it seems to work only with a specified value.
auto rng = v1 | ranges::views::filter([](int x){return ...;});
How can I do this without using for-loop?
