Lintcode运算符重载

实现赋值运算符重载函数，确保：

• 新的数据可准确地被复制
• 旧的数据可准确地删除/释放
• 可进行 A = B = C 赋值

class Solution {
public:
    char *m_pData;
    Solution() {
        this->m_pData = NULL;
    }
    Solution(char *pData) {
        this->m_pData = pData;
    }

    // Implement an assignment operator
    Solution operator=(const Solution &object) {
        // write your code here
        if(this != &object) {
          delete []m_pData;
          if(object.m_pData!=NULL) {
             m_pData = new char[strlen(object.m_pData)+1];
             strcpy(m_pData,object.m_pData);   
          }
        }
        return *this;
    }
};
