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 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;
* height; } void Box::set( double len, double bre, double hei) { length = len; breadth = bre...= 7.0; // box 2 详述 Box2.height = 10.0; Box2.length = 12.0; Box2.breadth = 13.0; /.../ box 1 的体积 volume = Box1.height * Box1.length * Box1.breadth; cout << "Box1 的体积：" << volume <<...endl; // box 2 的体积 volume = Box2.height * Box2.length * Box2.breadth; cout << "Box2 的体积："...所以您可以按照如下方式定义 getVolume() 函数： class Box { public: double length; // 长度 double breadth
." breadth = b; height = h; } double Volume()...{ return length * breadth * height; } int compare(Box box) { return this...->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(3.3,
我们使用关键字 class 定义 Box 数据类型，如下所示： class Box { public: double length; // 盒子的长度 double breadth...* height; } void Box::set( double len, double bre, double hei) { length = len; breadth = bre...= 7.0; // box 2 详述 Box2.height = 10.0; Box2.length = 12.0; Box2.breadth = 13.0; /.../ box 1 的体积 volume = Box1.height * Box1.length * Box1.breadth; cout << "Box1 的体积：" << volume <<...endl; // box 2 的体积 volume = Box2.height * Box2.length * Box2.breadth; cout << "Box2 的体积："
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。
." << endl; length = l; breadth = b; height = h; // 每次创建对象时增加 1...objectCount++; } double Volume() { return length * breadth * height;...} private: double length; // 长度 double breadth; // 宽度 double height;...// 每次创建对象时增加 1 objectCount++; } double Volume() { return length * breadth...getCount() { return objectCount; } private: double length; // 长度 double breadth
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]
