Is there an easier way to iterate through a vector from the back? [duplicate]

So, normally I'd iterate this way:

for(int i{ n - 1 }; i >= 0; --i) 

or like that:

for(size_t{v.size()-1}; i >= 0; --i) if(i > v.size()) break; 

or that:

for(int* i{ &v.back() }; i >= &v.front(); --i) 

But is there an easier/faster way to do that?

Here's the code, btw:

int n; cin >> n; vector<int> v(n); for (auto& e : v) cin >> e; int min = INT_MAX; int count{}; for (int* i{ &v.back() }; i >= &v.front(); i--) { if (*i > min) count++; min = ::min(min, *i); }
