Problem:
A: four tea
問題
プログラミングコンテストにはお茶が欠かせない。お茶にはコンテスタントの緊張を和らげる作用があるのだ [要出典]
コンテストに参加する選手が
N
人いるので、この人数分のお茶を用意したいと考えている。お茶のパッケージは
A
,
B
,
C
,
D
の 4 種類あり、どれも同じ品種であるが内容量が異なる。あるパッケージ
X
について、そのパッケージ 1 つ分の値段は
p_X
円であり、1 つ買うと
t_X
杯分のお茶を作れることがわかっている。
N
人分のお茶を作るために必要な金額の最小値を求めよ。なお、全く購入しないパッケージがあってもよく、ちょうど
N
人分になるようにパッケージを購入する必要もない (
N
人分以上作れれば良い)。
入力形式
入力は以下の形式で与えられる。
N
p_A
p_B
p_C
p_D
t_A
t_B
t_C
t_D
1
行目ではコンテストに参加する選手の人数が与えられる。
2
行目では、パッケージ
A
,
B
,
C
,
D
のお茶の価格が空白区切りで与えられる。
3
行目では、パッケージ
A
,
B
,
C
,
D
からお茶が何杯作ることができるか空白区切りで与えられる。
制約
1 \leq N \leq 100
1 \leq p_X \leq 100
1 \leq t_X \leq 100
全ての入力は整数として与えられる。
出力形式
