The time complexity of handling the operations in a data structure like a LINKED LIST are as follows:
i. Most of the operations are O(n) [i.e. omega times n]
ii. Remove/Insert operations that handles element between elements require O(1) [i.e. omega times one] this is due to references/pointers on both the ends of the list, hence the elements don't require to be shifted. However, due to the references/pointers this data structure requires additional memory!

Operation time complexity for an ARRAY
The time complexity of handling the operations in a data structure like an ARRAY are as follows:
i. Almost all the operations are O(1) [i.e. omega times one]
ii. Remove/Insert operations that handles element between elements require O(n) [i.e. omega times n] because the elements need to be shifted.
Note! Hence, an array as a data structure is used where remove/insert operations are not required.
