# PetscSortInt

Sorts an array of integers in place in increasing order.

### Synopsis

    #include "petscsys.h"
    PetscErrorCode  PetscSortInt(PetscInt n,PetscInt X[])

Not Collective

### Input Parameters

| n | - number of values
| X | - array of integers

### Notes

This function serves as an alternative to PetscIntSortSemiOrdered(), and may perform faster especially if the array is completely random. There are exceptions to this and so it is __highly__ recommended that the user benchmark their code to see which routine is fastest.
