The system is designed to allow client programs to call functions on the server, even if the client and server are written in different programming languages. To do this, I created our own basic Remote Procedure Call (RPC) route, a way for the client and server to communicate with each other over the network. the protocol used for RPC is JSON-RPC, a widely used format for sending data over a network.

Use Python for the server program and JavaScript for the client program via Node.js, which can run on an OS as well as a web browser.

The client sends a JSON file to the server as a request, and the server returns a JSON file as a response.

[Request]

{
  jsonrpc: '2.0',
  method: 'validAnagram',
  id: 1,
  params: [ 'hello', 'yellow' ]
}

[Response]

{
  jsonrpc: '2.0',
  result: false,
  id: 1
}

• floor(double x): Truncates the decimal number x to the nearest integer and returns the result as an integer.
• reverse(string s): takes a string s as input and returns a new string that is the reverse of the input string.
• validAnagram(string str1, string str2): Takes two strings as input and returns a boolean indicating whether the two input strings are anagrams of each other.
