Data processing method, client device, and non-transitory recording medium having a program recorded thereon

A data processing method executed by a server, the method comprising:

• receiving, from an outside of the server, input data which is data for designating a function expression and at least one type of operation to be executed using the function expression, the at least one type of operation being selected from one or more types of operations, without receiving a request for sharing a result of at least one operation corresponding to the received at least one type of operation;
• in response to the receiving the input data, executing the at least one operation based on the received input data, and transmitting at least one result of the executed at least one operation to the outside of the server, without storing the result of the executed at least one operation in a non-transitory memory;
• Re-receiving, from the outside of the server, the input data which is the data for designating the function expression and the at least one type of operation, and receiving the request for sharing the result of the at least one operation corresponding to the re-received at least one type of operation along with the input data;
• in response to the re-receiving the input data, re-executing the at least one operation corresponding to the re-received at least one type of operation, based on the re-received input data, and storing, in the non-transitory memory, a result of the re-executed at least one operation and at least one pointer corresponding to the result of the at least one operation one-to-one so that the result of the re-executed at least one operation is associated with the at least one pointer.
