Output

isAdded : true
After calling offer(4000) Method : linkedList : [200, 300, 10000, 5000, 2000, 4000]

isAdded : true
After calling offerFirst(100) Method : linkedList : [100, 200, 300, 10000, 5000, 2000, 4000]

isAdded : true
After calling offerLast(6000) Method : linkedList : [100, 200, 300, 10000, 5000, 2000, 4000, 6000]
