Description : Removes elementes from range [first, last) that satisfy a condition and returns a new past-the-end iterator for the new end of range.
Example:
auto isOdd = [](int i) {
return ((i%2) == 1);
};
std::vector<int> v {1, 2, 3, 4, 5};
// Remove all elements that returns true for isOdd
auto newEndIt = std::remove_if(v.begin(), v.end(), isOdd);
// Erase elements from [newEndIt, v.end()]
v.erase(newEndIt, v.end());
// v is now {2, 4}
for (auto value : v) {
std::cout << value << " ";
}
