I have been doing this code [Code Link](https://ideone.com/wPRFgQ)↵
↵
Problem is that when I iterating over keys to sort their vector, then sorting is not working properly.↵
Test Case:-↵
3 4[cut]↵
3 4 3 3[cut]↵
3 7 5 5[cut]↵
1 1 5 3[cut]↵
3 3 7 3[cut]↵
4 1 5 5[cut]↵
3 1 5 3[cut]↵
↵
Any idea why?↵
Thanks in advance:)
