refactor NGE_INC macro for improved robustness and operator precedence handling. The NGE_INC(x, y) macro was corrected to include additional parenthesis to ensure the proper order of operations. It now increments x by 1 and applies the modulo y correctly, ensuring consistent and error-free behavior, particularly in complex expressions
