Which of the following code snippets will sort a vectorv of integers in descending order by using the sort function from the $C++$ library?

sort$($v$.$begin$(),$ v$.$end$())$;

for $($int $i=0$; swap$(v[i],v[v*size()-1-i])i=0i++$swap$(v[i],v[v*size()-1-i])swap(v[i],v[v*size()-1-i])i=0i++v[i]=-v[i]i$; $i++i=0$;$ii$; $i++i$
