load balance

Implement a function to check whether the two fork tree is balanced, the balance is defined as follows, for any node in the tree, its two sub-tree height difference of not more than 1. Given a pointer to the root node treenode* root, return a bool, representing whether the tree is balanced.ImportJava.util.*;/*Public class TreeNode {int val = 0; TreeNode left = null; TreeNode right = null; Public TreeNode (int val) {this.val = val; }}*/ Public

function call. "The main module saves the return address on the stack when calling the exported function of the DLL (ESP-XXX). When a function call returns, the stack gets the return address (ESP + XXX), which returns to the main module. "Now understand, we call the function in the __cdecl way, the caller is responsible for the function of the stack, to ensure the stack balance, so we need to clear the stack after the call fun1, here according to the

There are 12 objects (eggs, iron, etc.), shapes, all of the same size. Among them, 11 of the same weight, the other 12 different. Today there is a balance point, you say 3 find some time, different objects (the weight of the object is different than the other 111 light or heavy unknown).Solving:The 12 objects are numbered sequentially from 1-12.watermark/2/text/ahr0cdovl2jsb2cuy3nkbi5uzxqvd29vzhk4ote=/font/5a6l5l2t/fontsize/400/fill/i0jbqkfcma==/ Diss

Test instructions: Title, the balance tree refers to any one node (except the leaves), the height of its left subtree and the height of the right sub-tree is not more than 1.Idea: recursive solution, but the function provided does not meet the requirements of recursion Ah, we have to know at least the height, but also to return to true and false, so another function to solve.1 /**2 * Definition for a binary tree node.3 * struct TreeNode {4 * int val;5

DescriptionNow is asked to measure a dose of medicine with a balance and a number of weights. Certainly it isn't always achievable. So-should find out the qualities which cannot is measured from the range [1,s]. S is the total quality of the weights.InputThe input consists of multiple test cases, and each case begins with a single positive integer N (1OutputFor each input set, you should first print a line specifying the number of qualities which cann

Martians: they can also change the string itself while taking LCQ functions. Specifically, you can change the value of one of the characters in a string, or you can insert a character at one point in the string. Earth people want to test, in such a complex question, whether the Martians can also be able to quickly find the value of the LCQ function.InputThe first line gives the initial string. The second line is a non-negative integer m that represents the number of operations. The next M-line,

Parallel Search. For example, in a group of red spheres looking for a blue ball, no matter how many red balls you add, subjects can find the object at almost the same speed (blue ball). Or when everything is stationary, we can quickly find the only
