Getting wrong answer in two cases

#1
#2

Hello @Jun18APP0112,

You are storing the elements of stack a in reverse order in the stack s
while(!a.empty()){
//cout<<a.top()<<endl;
//v.push_back(a.top());
if(i==q-1){
cout<<a.top()<<endl;
}
//The top of a will become the last element of s.
s.push(a.top());
a.pop();
}

Hope, this would help.
Give a like if you are satisfied.
