Here is the code:
func [] _ = 0
func (head:tail) num
| head > num = func tail num
| head <= num = head + (func tail num)
main = print(func [4,1,2,5,7,6] 2 * 3)
Here is my solution:
4 + func[1,2,5,7,6] 6 -> 1 + func[2,5,7,6] 6 -> 2 + func[5,7,6] 6 -> 5 + func[7,6] 6 -> func[6] 6 -> 6 + func[] 6 —> 4 + 1 + 2 + 5 + 6 = 18
But i checked in online compiler solution is 9, where did i make a mistake i don’t get it it’s pretty simple code
>Solution :
The expression providing the argument to print should be understood as
(func [4, 1, 2, 5, 7, 6] 2) * 3
not
func [4, 1, 2, 5, 7, 6] (2 * 3)
because function application takes precedence over any infix operator.
