What is the time complexity of dequeuing an element from a queue implemented using an array?

Step 1: Understand what 'dequeuing' means. Dequeuing is the process of removing an element from the front of a queue.
Step 2: Know that a queue can be implemented using an array. This means the elements are stored in a list format.
Step 3: When you remove the front element from the queue, the next element in the array needs to move to the front position.
Step 4: If there are 'n' elements in the queue, after removing the front element, you have to shift all 'n-1' elements one position to the left.
Step 5: Shifting 'n-1' elements takes time proportional to 'n', which is O(n) time complexity.
Step 6: Therefore, the time complexity of dequeuing an element from a queue implemented using an array is O(n).
