What is the time complexity of inserting at index n on an unsorted array?O(n!)O(2^n)O(1)O(n)O(nlog(n))O(n^2)O(log(n))
Question
What is the time complexity of inserting at index n on an unsorted array?O(n!)O(2^n)O(1)O(n)O(nlog(n))O(n^2)O(log(n))
Solution
The time complexity of inserting at index n on an unsorted array is O(n). This is because in the worst case scenario, you may need to shift all the elements to the right of the insertion point to make room for the new element. This requires a linear amount of work, hence the time complexity is O(n).
