Web1 day ago · Time and Space Complexity. The time complexity of the above code is O(Q*D*N), where Q is the number of queries. D is the size of each required subarray and N is the length of the array. The space complexity of the above code is O(N), as we are using an extra array to store the rotated array. Efficient Approach WebSo you have the right logic, if you have a loop of O ( n) iterations, the complexity of the entire loop will be O ( n ∗ complexity of loop operations). In this case, you again are correct that your loop's complexity is O ( n) for each iteration. brian sheath
