一般常用的转换字符串的方法std::stringstream,但是效率较低;目前C ++11提供了std::to_string 效率方面:C风格的sprintf()没有动态分配内存效率最高;std::to_string其次;std::stringstream效率最差 从C++17开始,std::to_string的效率将不差于sprintf,同时有类型更安全的转换函数std::to_char. 函数重载原型: l w string to_string(int val); l w string t
c++11中提供了to_string函数,定义在string中, 重载了一大片, std::string to_string( int value ); () (since C++) std::string to_string( long value ); () (since C++) std::string to_string( long long value ); () (since C++) std::string to_string( unsigned value ); () (sinc

Given a sorted integer array without duplicates, return the summary of its ranges. For example, given [0,1,2,4,5,7], return ["0->2","4->5","7"]. Credits: ============== 题目,返回数组范围的 集合. 思路: 模拟整个过程,利用标准库中提供了to_string函数, 就
