replace(beg, end, old_val, new_val);
Replace elements whose value is equal to old_val with new_val in iterator range [beg, end).
replace_if(beg, end, pred, new_val);
Replace elements whose return value is nonzero when calling predicate pred(val) with new_val in iterator range [beg, end).
replace_copy(beg, end, dest, old_val, new_val);
Copy elements in iterator range [beg, end) to iterator dest, and replace elements whose values are equal to old_val with new_val.
replace_copy_if(beg, end, dest, pred, new_val);
Copy elements in iterator range [beg, end) to iterator dest, and replace elements whose return value is nonzero when calling predicate pred(val) with new_val.
