Description : Return iterator to the first element in the range [first, last) that is equal to an element from the range [s_first; s_last). If no such element is found, last is returned.(Searches the range [first, last) for any of the elements in the range [s_first, s_last) ).
Example:
std::vector<int> v{0, 2, 3, 25, 5};
std::vector<int> t{3, 19, 10, 2};
auto result = std::find_first_of(v.begin(), v.end(), t.begin(), t.end());
if (result == v.end()) {
std::cout << "no elements of v were equal to 3, 19, 10 or 2\n";
} else {
std::cout << "found a match at "
<< std::distance(v.begin(), result) << "\n";
}
