thrust::sort

Defined in thrust/sort.h

template<typename RandomAccessIterator, typename StrictWeakOrdering> void thrust::sort(RandomAccessIterator first, RandomAccessIterator last, StrictWeakOrdering comp)

sort sorts the elements in [first, last) into ascending order, meaning that if i and j are any two valid iterators in [first, last) such that i precedes j, then *j is not less than *i. Note: sort is not guaranteed to be stable. That is, suppose that *i and *j are equivalent: neither one is less than the other. It is not guaranteed that the relative order of these two elements will be preserved by sort.

This version of sort compares objects using a function object comp.

The following code demonstrates how to sort integers in descending order using the greater<int> comparison operator.

#include <thrust/sort.h>
#include <thrust/functional.h>
...
const int N = 6;
int A[N] = {1, 4, 2, 8, 5, 7};
thrust::sort(A, A + N, thrust::greater<int>());
// A is now {8, 7, 5, 4, 2, 1};
