I did  in complexity of O(nlogn) and using vectors . I didn't knew why this happened as the with the given constraints my solution in nlogn should run! ↵

But on changing vectors to array format ,it worked!!!↵

As you can see there is only one difference of conversion of vector maxel to an array↵
↵
It would be kind if someone can tell how can this happen and where can i safely use a vector instead of an array.↵

thanks↵
