inplace pruning for a random-access iterator-sequence

The generated sequence will always contain the first and last pose. Use it in combination with erase, to obtain a pruned sequence.

Below some examples:

// create some data
std::vector<int> d {1, 2, 3, 4, 5};
 
// prune the data and drop redundant data
// d contains after this {1, 3, 5}
d.erase(prune(d.begin(), d.end(), 2), d.end());
 
// create another array
std::vector<int> e{1, 2, 3, 4, 5, 6};
 
// run again the same operation:
// e contains after this {1, 4, 6}
e.erase(prune(e.begin(), e.end(), 3), e.end());

Template Parameters

_Iter

random access iterator

Parameters

_begin	begin of the sequence
_end	end of the sequence
_step	positive integer for skipping

Returns

the end iterator of the pruned sequence
