The core idea of merge sorting is to merge the already sequenced A[p~q], and A[q~r] (where A is an array, p, Q, r array subscript) into a single sorted set of A[p~r]. The implementation code is as follows: void _merge (int * Input,int * output, int Low, int Mid, Span style= "color: #0000ff;" >int "{ int i = low; int J = mid; while (I high) { Output[low + +] = Input[i] ]; } copy ( input[i], input[mid], output[low]); Copy ( input[j], input[high], output[low]);} But to a
