I want to invite you to share your template code which you're using for Codeforces contests using Carbon(free and open-sourse) project. Mine (First but not Best!):

Hope you guys take care in this time of corona-related hardship!

Unsurprisingly, the length of the template has (from the examples so far) been inversely correlated with CF rating :^)

      I have no template at all (or, strictly speaking, here is my submission template:

      %Code%

int main() {
#ifdef LOCAL
        signal(SIGABRT, &signalHandler);
#endif
    std::ios::sync_with_stdio(false);
    std::cin.tie(0);
#ifdef LOCAL_RELEASE
    freopen("input.txt", "r", stdin);
    freopen("output.txt", "w", stdout);
    auto time = clock();
#endif
	%ClassName% solver;
	%Input%
	%Output%
	%SolverCall%
	fflush(stdout);
#ifdef LOCAL_RELEASE
	cerr << clock() - time << endl;
#endif
	return 0;
}

      ). I do use inliner though

            If not, Can you please give a link to it? Thanks in advance.

      You really can't consider that a template. It's an algorithm library. For example, you can't compile that as is (variable names are reused, etc.). I use KACTL (https://github.com/kth-competitive-programming/kactl), which also has a ton of lines of code total, but doesn't have a very long template.

    Maybe you're not compiling with the correct preprocessor directive? Your code snippet seems to require LOCAL_RELEASE to be defined.

    You can call both power1 and power2 power; the difference in header will overload the function signature and the version called will just depend on whether you pass in the mod argument. Also, it probably won't matter because ll overflow is rare, but you may want to rewrite the lcm argument as (x/gcd(x,y))*y to prevent x*y from overflowing.

    Hi. I see you are using c++17 on cf. I'd like to tell you about one funny thing. Your template has lcm function which is defined for long longs, but c++17 has it's own function with the same name, so it replaces yours with the std one. Why does it matter? Std function's return type is the same as argument type, so if you run

    cout << lcm(1000000000, 1000000000 - 1);

    You will see 1808348672( overflow ), because args are of type int. It's very tricky, isn't it? Here's how you can fix it:

    1. add #define lcm(x, y) lcm((ll)(x), (ll)(y)) instead of implementing your own lcm function

    2. add #define lcm randomlongstringwhichyouwillneveruseasanameorsomethinglikethat after including libraries, this way your function will be used

    p. s. talking about lcm I suggest that shahil_005 throws that weird-ass lcm function out of his template there are so many things wrong with it

    UPD: soumitri2001 you have fucked up lcm function as well(but for a different reason. Change (long) (a*b/gcd(a,b)) to (long) ((long)a*b/gcd(a,b)). The a*b part gives you overflow

      I would just do 

      #define gcd(a, b) ggcd(a, b)

      where the function ggcd has the gcd function.

This is mine, I saw Geothermal use it in his Div. 3 unofficial editorial and thought it was good and that I wouldn't have to change it for a long period of time, and so far it's served me really well. Though I made a few edits of my own. Pastebin link because I just can't get carbon to upload the template

You can avoid to use macro CONFIG:

const bool ready = [](){
    std::ios_base::sync_with_stdio(false); std::cin.tie(0);
    std::cout << std::fixed << std::setprecision(12);
    return true;
}();

This lambda will be called before main. Example

    The followng is a slight update that uses auto as the return type of the expression.
