# PetscSortIntWithIntCountArrayPair
Sorts an array of `PetscInt` in place in increasing order; changes a `PetscInt`  array and a `PetscCount` array to match the sorted first array. 
## Synopsis
```
#include "petscsys.h"  
PetscErrorCode PetscSortIntWithIntCountArrayPair(PetscCount n, PetscInt X[], PetscInt Y[], PetscCount Z[])
```
Not Collective


## Input Parameters

- ***n  -*** number of values
- ***X  -*** array of integers
- ***Y  -*** second array of integers (first array of the pair)
- ***Z  -*** third array of PetscCounts  (second array of the pair)





## Note
Usually X, Y are matrix row/column indices, and Z is a permutation array and therefore Z's type is PetscCount to allow 2B+ nonzeros even with 32-bit PetscInt.
