Update BottomUpRodCut.java

[mosishon]

اگر شمارنده حلقه اول (l) از شماره 2 شروع بشه، نیازه که قبل از حلقه r[1] رو پر کنیم
در غیر اینصورت چون مقدار پیشفرض 0 قرار گرفته. هزینه r[1] رو صفر در نظر میگیره.
پس مقدار خونه r[1] رو دستی از جدول p میخونیم و قبل از حلقه پر میکنیم

I appreciate your correct idea, but if you look more carefully at the previous if-statement, this assignment has been applied.
If i want to explain in more detail, the first if-statment inside bottomUpRodcut function (method 1):

if (n <= 1) {
    r[n] = p[n];
}

checks if n is equal to zero or one then assign corresponding element to these indices in p-array ( price array ) to r-array. In other word, if n = 0 then r[0] = p[0] or if n = 1 then r[1] = p[1].

*And it's correct for rod with length of one that have price 1. otherwise you'r correct.
Thank you.
