I have set 2 variables largest and secondLargest .Then iterated list with for loop and compare ith element with largest and secondLargest and changed them accordingly. Finally returned secondLargest.
I took a dictionary and stored occurence of every elements from list. Then took a list as ans and iterated given list and checked if its occurence is 1 with dictionary if occurence is 1, then add that element in ans. Finally return ans list.
