please wait i am trying to debug

#3 
vector<int> vec(nums.size() , -1);
        stack<int> st;
        st.push(0);
        int n = nums.size();
        for(int i = 1 ; i < 2*n ; i++){
            while(!st.empty() and nums[i%n] > nums[st.top()]){
                vec[st.top()] = nums[i%n]; st.pop();
            }
                st.push(i%n);
        }

hi @navin_japes
this much of code would do the entire work
just print the result vector at the end
