Optimized for Gas Efficiency: Removed the need to store the cube result (cube_), saving gas. Instead, getCube is a pure function, which calculates and returns the result without modifying the contract’s state.
Input Validation: Added a check to ensure _number is small enough to prevent overflow during cube calculation.
Flexible Interface: getCube calculates the cube directly without modifying the state, and setAndCube can be used if the input needs to be stored in number.
