shared_ptr的循环的资源泄漏先上代码class A :public enable_shared_from_this<A>{ public: A() { cout << "A create" << endl; } ~A() { cout << "A dele" << endl; } void son_ge

1.整数的二进制位奇数位和偶数位交换#define CHANGE(X)\ ((((X) & (0x55555555)) << 1) | (((X) & (0xaaaaaaaa)) >> 1))

目的实现供应商供应和的一个统计表需要的库python -m pip install -U matplotlib这是图形库python -m pip install -U openpyxl这是操作xlsx的库（数据来源是xlsx文件）在开始之前，我们先引入头文件import matplotlib.pyplot as plt#plt是我们的画板from openpyxl import load_workbook先打开我们需要读取的xlsx文件wb = load_workbook('

平衡二叉树自己看书上定义。直接上源码若方法没写全，后续会补上。public class BTS<Key extends Comparable<Key>,Value> { private class Node { private Key key; //键,用于比较，用Comparable类的子类来进行比较 private Value val; //值 private Node left; private Node rig
