Martian Dollar

一天Vasya得到了接下来n天，在bourles 有火星元的交易的信息。 第i天每一火星元的市价（不管是买入还是卖出都一样）是a[i]. Vasya有b 火星元。 他可以执行至多一次买入一定数量的火星元并卖出的操作。 根据火星法律，对火星元的买卖必须以整数为单位。试问Vasya在过了n天后最多能得到多少火星元？ 输入格式： 第一行两个数$n,b (1 <= n,b <= 2000)$ ， 第二行，n个数a[i] $ 1 <= a_i<= 2000$ ，含义如题 输出格式： 一行一个数，表示答案。 Translated by @Maniac丶坚果

One day Vasya got hold of information on the Martian dollar course in bourles for the next $ n $ days. The buying prices and the selling prices for one dollar on day $ i $ are the same and are equal to $ a_{i} $ . Vasya has $ b $ bourles. He can buy a certain number of dollars and then sell it no more than once in $ n $ days. According to Martian laws, one can buy only an integer number of dollars. Which maximal sum of money in bourles can Vasya get by the end of day $ n $ ?

The first line contains two integers $ n $ and $ b $ ( $ 1<=n,b<=2000 $ ) — the number of days and the initial number of money in bourles. The next line contains $ n $ integers $ a_{i} $ ( $ 1<=a_{i}<=2000 $ ) — the prices of Martian dollars.

Print the single number — which maximal sum of money in bourles can Vasya get by the end of day $ n $ .
