-/*!
- * Returns a new DataArrayInt containing a renumbering map in "Old to New" mode computed
- * from a zip representation of a surjective format (returned e.g. by
- * \ref MEDCoupling::DataArrayDouble::findCommonTuples() "DataArrayDouble::findCommonTuples()"
- * for example). The result array minimizes the permutation. <br>
- * For more info on renumbering see \ref numbering. <br>
- * \b Example: <br>
- * - \a nbOfOldTuples: 10
- * - \a arr : [0,3, 5,7,9]
- * - \a arrIBg : [0,2,5]
- * - \a newNbOfTuples: 7
- * - result array : [0,1,2,0,3,4,5,4,6,4]
- *
- * \param [in] nbOfOldTuples - number of tuples in the initial array \a arr.
- * \param [in] arr - the array of tuple indices grouped by \a arrIBg array.
- * \param [in] arrIBg - the array dividing all indices stored in \a arr into groups of
- * (indices of) equal values. Its every element (except the last one) points to
- * the first element of a group of equal values.
- * \param [in] arrIEnd - specifies the end of \a arrIBg, so that the last element of \a
- * arrIBg is \a arrIEnd[ -1 ].
- * \param [out] newNbOfTuples - number of tuples after surjection application.
- * \return DataArrayInt * - a new instance of DataArrayInt. The caller is to delete this
- * array using decrRef() as it is no more needed.
- * \throw If any value of \a arr breaks condition ( 0 <= \a arr[ i ] < \a nbOfOldTuples ).
