thrust

◆ max_element() [2/4]

template<typename ForwardIterator >
ForwardIterator thrust::max_element ( ForwardIterator  first,
ForwardIterator  last 
)

max_element finds the largest element in the range [first, last). It returns the first iterator i in [first, last) such that no other iterator in [first, last) points to a value larger than *i. The return value is last if and only if [first, last) is an empty range.

The two versions of max_element differ in how they define whether one element is greater than another. This version compares objects using operator<. Specifically, this version of max_element returns the first iterator i in [first, last) such that, for every iterator j in [first, last), *i < *j is false.

Parameters
firstThe beginning of the sequence.
lastThe end of the sequence.
Returns
An iterator pointing to the largest element of the range [first, last), if it is not an empty range; last, otherwise.
Template Parameters
ForwardIteratoris a model of Forward Iterator, and ForwardIterator's value_type is a model of LessThan Comparable.
