replacedrng | boost::adaptors::replaced( new_value, old_value )boost::make_replaced_range( rng, new_value, old_value )
new_value is convertible to the value-type of
the range.
old_value is convertible to the value-type of
the range.
x in the returned range, the value
x is equal to the value of
(y == old_value) ? new_value : y
where y is the corresponding element in the original
range.

int main(int argc, const char* argv[])
{
using namespace boost::adaptors;
using namespace boost::assign;
std::vector<int> input;
input += 1,2,3,2,5,2,7,2,9;
boost::copy(
input | replaced(2, 10),

}
This produces the output:
1,10,3,10,5,10,7,10,9
