recursion

问题 Find the bellow parent child tree object I have created. I need to find the root parent of a given child id. For example child id - 242 root parent id is 238. There are similar questions have been asked and this is the one I found very similar to my question. Convert parent-child array to tree I have change the original code a bit But not working for child element. The issue is here. when it comes the recursive function with rootNode.children for loop will not execute since it does not loop

问题 I'm looking to take some code I've written in Java for a binary tree class and remove the count parameter from the arguments, but keep the whole thing recursive. So, given a class with these variables: public class BinaryTree<E> { protected E data; protected BinaryTree<E> left,right; How could I do that for: public int levelCount(int count, int level){ if (data == null) {return 0;} if (count == level) {return 1;} else { return this.getRight().levelCount(count+1,level) + this.getLeft()

问题 I want to write a recursive method to compute x^0 + x^1 + x^2 + ... x^n and then i want to display the values for the computed x^n ex: n = 3 and x =3 the output should be : 1 + 3 + 9 + 27 I have code to compute a recursive method like this but how do i use that method to print each iteration? My code is : public static double compute(int n, int x){ if(n == 0){ return 1; } else{ return Math.pow(x , n) + compute(x , n-1); } } 回答1: Try this as an alternative. The key is to save the return from
