The program codes embodied on the readable storage medium may be transmitted by any appropriate medium, including but not limited to wireless, wireline, optical fiber cable, RF, etc., or any suitable combination of the foregoing.
The program codes for executing the operations of the present disclosure may be written in any one or a combination of more of programming languages, including an object-oriented programming language such as Java and C++, and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The program codes may execute entirely on users' computing device, partly on the users' device, as a stand-alone software package, partly on users' computing device and partly on a remote computing device, or entirely on a remote computing device or server. In scenarios involving a remote computing device, the remote computing device may be connected to the users' computing device through any type of network, including local area network (LAN) or wide area network (WAN), or may be connected to an external computing device (for example, connected through Internet using an Internet Service Provider).
The above embodiments further illustrate the objectives, the technical solutions and the beneficial effects of the present disclosure in detail. It should be understood that the present disclosure is not inherently related to any particular computer, virtual apparatus or electronic device, and various general-purpose apparatuses also may implement the present disclosure. The above are merely preferred embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc., made within the spirit and principle of the present disclosure, shall be covered within the scope of protection of the present disclosure.
