int入力nが与えられた場合、n *を反転して出力する。

Given an integer n, print out n *
reversed(n)

reversed(n) is the number you get when you
reverse the digits of n.


reverse(512) = 215

reverse(1) = 1

reverse(101) = 101

>>>>>>>>

func(5) = 5*5 = 25

func(12) = 12*21 = 252

func(11) = 11*11 = 121

func(659) = 659*956 = 630004

最短コードが勝ちます!

R*

オンラインで試してみてください!

05AB1Eでは、整数と文字列は同等の型として扱われるため、反転( R
)は文字列と逆転に変換され、乗算( * )は逆と入力を整数。
