golang list to tree

To convert a list to a tree in Go, you can use recursion. Here is an example implementation:

type Node struct {
    Value int
    Left  *Node
    Right *Node
}

func ListToTree(lst []int) *Node {
    if len(lst) == 0 {
        return nil
    }

    mid := len(lst) / 2
    node := &Node{Value: lst[mid]}
    node.Left = ListToTree(lst[:mid])
    node.Right = ListToTree(lst[mid+1:])
    
    return node
}

This function takes in a sorted list of integers and recursively constructs a binary search tree from it. The middle element of the list is chosen as the root of the current subtree, and the left and right subtrees are recursively constructed from the elements on either side of the middle element.

For example, given the list [1, 2, 3, 4, 5], this function would construct the following binary search tree:

      3
     / \
   1     4
    \     \
     2     5
