在这篇博客http://blog.csdn.net/hacker_zhidian/article/details/54774013中的问题我们采用了深度优先搜索...
第二种是广度优先遍历（Breadth First Search)，也有称为广度优先搜索，简称为BFS。我们在《队列与广度优先搜索》中已经较为详细地讲述了广度优先搜索的策略，这里不再赘述。

import UIKit struct Area { var length = 0 var breadth = 0 func area() -> Int { return length * breadth } mutating func scaleBy(res: Int) { length *= res breadth *= res print("length:\(length)","breadth:\(breadth)") print("area:", area()); } } var val = Area(length: 3, breadth: 5) val.scaleBy(res: 3) 打印 length:9 breadth:
data_type } 例子 package main import ( "fmt" ) type rectangle struct { length float64 breadth = 19 rec.length = 23 rec.color = "Green" rec.geometry.area = rec.length * rec.breadth rec.geometry.perimeter = 2 * (rec.length + rec.breadth) fmt.Println(rec) fmt.Println("Area:\t } func main() { rect1 := new(rectangle) rect1.length = 10 rect1.breadth = 20 rect1. color = "Green" fmt.Println(rect1) rect2 := new(rectangle) rect2.breadth = 20 rect2.
用来描述一个盒子 #include <iostream> using namespace std; class Box { public: double length; // 定义长度 double breadth = 7.0; box1.height = 5.0; // 第二个盒子 box2.length = 10.0; box2.breadth = 10.0; box2.height = 10.0 ; // 第一个盒子的体积 volume = box1.length * box1.breadth * box1.height; cout << "第一个盒子的体积" << volume << endl; // 第二个盒子的体积 volume = box2.length * box2.breadth * box2.height; cout << "第二个盒子的体积" << volume ; // 定义宽度 double height; // 定义高度 double getVolume(void){ return length * breadth * height;
." << endl; length = l; breadth = b; height = h; } double Volume () { return length * breadth * height; } int compare(Box box) { Volume() > box.Volume(); } private: double length; // Length of a box double breadth ; // Breadth of a box double height; // Height of a box }; int main(void) { Box Box1
表达式 案例（将其保存为 expression.py）： length = 5breadth = 2area = length * breadth print('Area is', area) print ('Perimeter is', 2 * (length + breadth)) 输出： $ python expression.py Area is 10Perimeter is 14 它是如何工作的 矩形的长度（Length）与宽度（Breadth）存储在以各自名称命名的变量中。 我们将表达式 length breadth 的结果存储在变量 area 中并将其通过使用 print 函数打印出来。 在第二种情况中，我们直接在 print 函数中使用了表达式 2 (length + breadth) 的值。 同时，你需要注意到 Python是如何漂亮地打印出 输出结果的。
其英文全称为Breadth First Search，简称BFS。 self.node_neighbors[v].append(u) def nodes(self): return self.node_neighbors.keys() def breadth_first_search g.add_edge((3, 6)) g.add_edge((3, 7)) g.add_edge((6, 7)) print ("Original nodes: ", g.nodes()) order = g.breadth_first_search (1) print ("Breadth-First-Search order: ", order) 运行结果： Original nodes: dict_keys([1, 2, 3, 4, 5, 6, 7, 8]) Breadth-First-Search order: [1, 2, 3, 4, 5, 6, 7, 8]

#include <iostream> class Box { public: double getVolume(void) { return length * breadth * height ; } void setLength(double len) { length = len; } void setBreadth(double bre) { breadth } Box operator+(const Box& b) { Box box; box.length = this->length + b.length; box.breadth = this->breadth + b.breadth; box.height = this->height + b.height; return box; } private: double length; double breadth; double height; }; int main() { Box Box1; Box
def breadth(self): if self.root is None: #首先判断根节点是否为空，为空则返回 return queue=[self.root]#将根节点放入队列中 t.add(1) t.add(2) t.add(3) t.add(4) t.add(5) t.add(6) t.add(7) t.add(8) t.breadth ()#调用breadth方法，打印二叉树# 输出结果：#0 1 2 3 4 5 6 7 8 结语 本文主要介绍了如何用python来实现二叉树的操作，主要利用了队列元素的取出，判断，增添来实现。
表达式 示例（保存为 demo.py）： ''' version = 1.0 author = 剑指工控 ''' length = 5 breadth = 2 area = length * breadth print('Area is', area) print('Perimeter is', 2 * (length + breadth)) 输出： > python demo.py Area is 10 Perimeter is 14 它的工作原理 矩形的长和宽分别保存在变量 length 和 breadth 中。 我们将表达式 length * breadth 的计算结果保存到变量 area 中，然后用 print 函数将其打印输出。 第二种情况是，我们直接在 print 函数中使用表达式 2 * (length + breadth) 的值。 请注意一下 ： Python 打印输出结果。
"collect_mode" : "breadth_first" depth_first 直接进行子聚合的计算 breadth_first 先计算出当前聚合的结果，针对这个结果在对子聚合进行计算。 "field": "sin_id", "execution_hint": "map", "size": 1000, "collect_mode": "breadth_first
_breadth = y; } Rectangle.prototype.getDimensions = function(){ return { length: this. _length, breadth: this. _breadth }; };var x = new Rectangle(3, 4);var y = new Rectangle(4, 3);console.log(x.getDimensions ()); // { length: 3, breadth: 4 }console.log(y.getDimensions()); // { length: 4, breadth: 3 } 代码中，x和y
