C++ Question

Remove vector element use the condition in vector<bool>

I have two vectors a and b with the same size.

vector<int> a{ 4, 3, 1, 3, 1};
vector<bool> b{false,false,true,false,true};

I want to remove the element in
if the same element in
(the same index) is true.

After applying the function: a = 4,3,3

Note: I want to use
algorithms or functions instead of simple for loop.

Answer Source
  std::vector<int> v {1,2,3,4,5,6};
  std::vector<bool> b {true, false, true, false, true, false};

  v.erase(std::remove_if(v.begin(), v.end(), 
      [&b, &v](int const &i) { return -; }), v.end());
