Improved prompt:

CRAFT A COMPLETE C++ PROGRAM THAT EFFICIENTLY SOLVES THE FOLLOWING PROBLEM, USING THE STANDARD NAMESPACE ("STD") IN A CLEAN AND ELEGANT MANNER:

PROBLEM OVERVIEW:
[DETAILED DESCIPTION OF THE PROBLEM TO BE SOLVED INCLUDES INPUT/OUTPUT SPECIFICATIONS, CONSTRAINTS, AND ANY RELEVANT ALGORITHMIC INFORMATION]

PROGRAM SPECIFICATIONS:

• The program must be written in C++ and utilize the standard namespace (std) exclusively.
• The solution must be highly efficient, prioritizing performance over verbose code.
• The code should have no comments, with a zero-space gap between operators and operands to minimize visual clutter.
• Maintain proper margin and indentation for readability, with opening brackets always starting on the next line.
• Rename all variables to be as short as possible, preferably using single lowercase alphabets.

DELIVERY FORMAT:

• The solution should be presented in a single, well-formatted code block without any additional text.
• Ensure that the provided code is fully functional when compiled and executed in a standard C++ environment.

NOTES:

• This prompt is designed to evaluate your ability to craft highly optimized and clean C++ code from a problem description.
• The solution must be delivered in a style that reflects the essence of modern, efficient C++ programming.
• Avoid any unnecessary complexity or redundant code elements.

Please provide the requested C++ solution, adhering strictly to the specified guidelines.
