In C++ (Remove elements) Implement the following function that removes the specified value from a first-class container. Only the first occurrence of a matching value in the container is removed.

template void remove(ContainerType& container, const ElementType& value)

Your sample case should push the integer 1 through 6 onto a vector, display the contents of the vector, remote the integer 4 from the vector, display the vector again, and attempt to remove the integer 4 a second time, gracefully handling the error when the element is not found.
