According to the C++ standard, comparison functions used in sorting algorithms such as std::sort must establish a strict weak ordering. Specifically, the comparator must be irreflexive: for all values x, comp(x, x) must be false. The original comparator used >= for descending order, which violates this requirement in the case of equal values (i.e., when a == b, both comp(a, b) and comp(b, a) would return true). This can result in undefined behavior in sorting algorithms, including potential segmentation faults due to invalid iterator manipulation. This change replaces >= with > to ensure irreflexivity and compliance with the standard's requirement for a strict weak ordering.
