Maybe this is problem with Eq and Ord

yep, my code for this case return false

Hi, i have some problem with this signature of option

  trait SOption[+A] {
    def apply[B]: (=> B, A => B) => B
  }

when i try implement
fromOption
they always say that i have problem with this part

=> B,

maybe it must be simple B

Do you can apply translation for scala language?

Do you can apply translation for scala language?

In description need add how work with floating part, truncate or round ceil.

Test case in rust not cover condition "until the nth year" (when year = 0),
and most decision is wrong

I think this part of code has a mistake if n == 0 { because the condition says "until the nth year"

I have error in random money..

(count-change 0 [1 6])
expected: (= (count-change money coins) (my-count-change money coins)) - actual: (not (= 0 1))

i think if you don't have money you can change it 0 type posebillety, or not?

Thx)

Hello, i try to complete kata, but test has error on code ",>+>>>>++++++++++++++++++++++++++++++++++++++++++++>++++++++++++++++++++++++++++++++<<<<<<[>[>>>>>>+>+<<<<<<<-]>>>>>>>[<<<<<<<+>>>>>>>-]<[>++++++++++[-<-[>>+>+<<<-]>>>[<<<+>>>-]+<[>[-]<[-]]>[<<[>>>+<<<-]>>[-]]<<]>>>[>>+>+<<<-]>>>[<<<+>>>-]+<[>[-]<[-]]>[<<+>>[-]]<<<<<<<]>>>>>[++++++++++++++++++++++++++++++++++++++++++++++++.[-]]++++++++++<[->-<]>++++++++++++++++++++++++++++++++++++++++++++++++.[-]<<<<<<<<<<<<[>>>+>+<<<<-]>>>>[<<<<+>>>>-]<-[>>.>.<<<[-]]<<[>>+>+<<<-]>>>[<<<+>>>-]<<[<+>-]>[<+>-]<<<-]"

I must find the closest parentheses or take into account the nesting ?
thanks
