JavaScript实现树的遍历算法示例【广度优先与深度优先】
sjiang 人气:0本文实例讲述了JavaScript实现树的遍历算法。分享给大家供大家参考,具体如下:
<script type="text/javascript"> var t = [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19]; //下面这段深度优先搜索方法出自Aimingoo的【JavaScript语言精髓与编程实践】 var deepView = function(aTree,iNode) { (iNode in aTree) && (document.write(aTree[iNode]+'<br/>'),arguments.callee(aTree,2*iNode+1),arguments.callee(aTree,2*iNode+2)) } //广度优先 var wideView = function(aTree,iNode) { var aRTree = aTree.slice(0),iRNode = iNode,iLevel = 1; (iRNode in aRTree) && document.write(aRTree[iRNode]+'<br/>'); (function() { var iStart = iRNode*2+1,iEnd = iStart+Math.pow(2,iLevel); document.write(aRTree.slice(iStart,iEnd).join(',')+'<br/>'); if(iEnd>=aRTree.length) return; iRNode = iStart,iLevel++,arguments.callee(); })() } document.write('<h3>二叉树 深度优先</h3>'); //深度优先 deepView(t,0); document.write('<h3>二叉树 广度优先</h3>'); //广度优先 wideView(t,0); </script>
运行结果:
希望本文所述对大家JavaScript程序设计有所帮助。
