Example code sharing of how Javascript converts an array from small to large into a binary search tree

This article mainly introduces the relevant information of Javascriptconverting arraysfrom small to large into binary searchtrees. Friends in need can refer to the following

Without further ado, I will post the code directly for you. The specific code is as follows:

var Array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; 
var Tree = createTree(Array); 
console.log(Tree); 
// 构造一个节点 
function Node(nodeData, leftData, rightData) { 
  this.nodeData = nodeData; 
  this.leftData = leftData; 
  this.rightData = rightData; 
} 
// 每次取中点作为根节点,向左和向右递归 
function createTree(array) { 
  if (array.length <= 0) { 
    return null; 
  } else { 
    var mid = parseInt(array.length / 2); 
    var node = new Node(array[mid], null, null); 
    var leftArray = array.slice(0 , mid); 
    var rightArray = array.slice(mid + 1 , array.length ); 
    node.leftData = createTree(leftArray); 
    node.rightData = createTree(rightArray); 
    return node; 
  } 
}
