C++ in Competitive Programming: compromises--Marco Arena

By Marco Arena | Sep 30, 2016 10:27 AM | Tags: intermediate

In this installment I'll explain what I consider the essence of Competitive Programming:

C++ in Competitive Programming: compromises

by Marco Arena

From the article:

Crafting software is about balancing competing trade-offs. It’s impossible to optimize every factor of a system, as speed, usability, accuracy, etc at the same time. Moreover, solutions of today impact decisions and solutions of tomorrow. On the other hand, in Competitive Programming, the best solution is one that just makes each test-case pass...

The Case for Optional References--Tristan Brindle

And why not simply use a pointer?

The Case for Optional References

by Tristan Brindle

From the article:

I have a confession to make. Whenever I’ve come across code that looks like this:

struct example {
    example() = default;

    example(std::string& s) : str_{s} {}

private:
    boost::optional<std::string&> str_{};
};

there is a little voice inside my head that whispers “why didn’t you just use a pointer?”. Like so, for instance:

struct example {
    example() = default;

    example(std::string& s) : str_{&s} {}

private:
    std::string* str_ = nullptr;
};

This is equivalent to the first example, except that it’s slightly less typing, it doesn’t have any dependencies, and feels in some sense “cleaner”. I personally have always preferred it.

Except, I was wrong. After attending Bjarne Stroustrup’s keynote and this excellent talk at Cppcon this morning, I’m persuaded that optional references are a good thing. In this post I hope to be able to convince you of the same...
