 /**
  * @brief Performs a merge sort on a range of elements.
  * @param begin An iterator to the beginning of the range to be sorted.
  * @param end An iterator to the end of the range to be sorted.
- * @details This function sorts the elements in the range [begin, end) into ascending order.
- * The sort is performed in-place. It divides the range into two halves, recursively sorts each half,
- * and then merges the two sorted halves together. The function requires that the range of elements
- * is sortable by the criteria used in std::inplace_merge.
