The time complexity of inserting an element at the end of an array using shifting is O(n), where n is the number of elements in the array.
When inserting an element at the end of an array using shifting, we need to shift all the existing elements to make space for the new element. This shifting operation requires iterating through each element in the array and moving it one position to the right. Therefore, the time complexity is directly proportional to the number of elements in the array.
In the worst-case scenario, where the array is already full and we need to shift all elements, the time complexity will be O(n). However, if the array has empty spaces at the end, the time complexity can be reduced to O(1) as we can directly insert the element without shifting any elements.
It is important to note that if we are using a dynamic array, the time complexity of inserting an element at the end can be amortized to O(1) on average. This is because dynamic arrays can dynamically resize themselves when needed, allowing for constant time insertion at the end most of the time.
