hello!
I am stuck with this problem.
See the code below
class BuildingHeightsEasy
{
public:
struct node
{
int val;
int i;
};
bool myf(node p,node q)
{
return p.val<q.val;
}
int minimum(int M, vector > heights)
{
vector v;
sort(v.begin(),v.end(),myf); //THIS IS THROWING AN ERROR
}
if this is out of the class,then program is successfully compiled.Whats the problem??
