What is the time complexity of enqueueing an element in a queue implemented using an array?
Step 1: Understand what 'enqueueing' means. It is the process of adding an element to the end of a queue.
Step 2: Know that a queue can be implemented using an array, which is a fixed-size collection of elements.
Step 3: When you enqueue an element, you need to place it at the next available position in the array.
Step 4: If there is space available in the array (meaning the array is not full), you can directly add the new element.
Step 5: Adding an element to the end of the array takes a constant amount of time, regardless of how many elements are already in the queue.
Step 6: Therefore, the time complexity for enqueueing an element in this case is O(1), which means it takes the same amount of time no matter how many elements are in the queue.
