(src/template/debug.hpp)

debug

debug(hoge)

変数 hoge の行数，名前，中身を表示するデバッグマクロです．

debug(hoge, fuga, piyo)

などのように複数入力しても大丈夫です．

int 型などの数値型だけでなく pair 型や vector 型や map 型や set 型や bitset 型や modint 型にも対応しています．
UnionFind や Graph や FenwickTree などの構造体には現状では対応していません．

make b の際に debug が含まれる行が削除されます．
#include "template/debug.hpp" や debug(hoge) を消す目的ですが，以下のように書いてしまうと消えるべきでない行が消えてしまうので注意が必要です．
また”debug”という連続部分文字列を含む変数や関数の宣言にも気をつけてください．

int n = 5; debug(n);

modint 型のデバッグに対応させるために，内部で template/static_modint.hpp と template/dynamic_modint.hpp をインクルードしています．
#include "template/debug.hpp" をすると自動で modint 型が使えるようになりますが make b の際に内部インクルードが削除されるので， main.cpp 内でも modint をインクルードすることを忘れないようにしてください．
