Tree Recovery POJ - 2255 根据树的前序遍历和中序遍历还原后序遍历. (偷懒用了stl的find) #include<iostream> #include<string> using namespace std; string s1,s2; int len; void work(int l1,int r1,int l2,int r2) { if(l1==r1) { cout<<s1[l1]; return; } if(l1>r1) retur…

前序和中序输入二叉树,后序输出二叉树:核心思想只有一个,前序的每个根都把中序分成了两部分,例如 DBACEGF ABCDEFG D把中序遍历的结果分成了ABC和EFG两部分,实际上,这就是D这个根的左右子树,而接下来的B,把ABC分成了A和C两部分,那么,A,C实际上是B的左右子树而E把EFG分成了空集和FG两部分,也就是说,E只有右子树,F把FG分成了空集和G两部分,即F只有右子树G.个人认为理解了思路以后,最重要的细节就是遍历 前序遍历 的结果时,你的那个p的增加(这里的P指的是要把前序遍历…
