Nice teaching technique in easy language with example, but in the last example
reverse(v.begin(), v.begin() + 2) will come if we want to reverse the first two element.
If we want to reverse the whole string then we are giving reverse(v.begin(), v.end()), in reverse syntax second element will be last element + 1. that why we are giving v.end() that represent imaginary 0 after last element.
similarly, if we want to reverse the first two element then second parameter will be v.begin()+2.
