/* VAR_TPAは尺取り法用の変数名の接頭辞で、実際の変数名ではなく、_Lと_Rと_infoがつく。
ANSWER ## _temp = {VAR_TPA ## _L,VAR_TPA ## _R,VPA_TPA ## _info}を
{INIT,INIT,INFO_init}で初期化する。VPA_TPA ## _infoは区間和など。
ANSWER ## _tempがCONTINUE_CONDITIONを満たす限り、ANSWER ## _tempが
条件ON_CONDITIONを満たすか否かを判定し、それがtrueになるか
VAR_TAR ## _LがVAR_TAR ## _Rに追い付くまでVAR_TPA ## _LとVPA_TPA ## _infoの
更新操作UPDATE_Lを繰り返し、その後VAR_TPA ## _RとVPA_TPA ## _infoの
更新操作UPDATE_Rを行う。（マクロとコンマの制約上、関数オブジェクトを用いる）
ON_CONDITIONがtrueとなる極大閉区間とその時点でのinfoをANSWERに格納する。
例えば長さNの非負整数値配列Aで極大な正値区間とそこでの総和を取得したい場合
auto update_L = [&]( int& i_L , auto& i_info ){ i_info -= A[i_L++]; };
auto update_R = [&]( int& i_R , auto& i_info ){ if( ++i_R < N ){ i_info += A[i_R]; } };
TPA( interval , i , 0 , i_R < N , update_L( i_L , i_info ) , update_R( i_R , i_info ) , A[i_L] > 0 && A[i_R] > 0 , ll( A[0] ) );
とすればtuple<int,int,ll>値配列intervalに{左端,右端,総和}の列が格納される。
