To expand, shifting right by c bits, is deleting the c most significant bits. Shifting left by c bits, is simply adding c trailing 0s, so all in all c operations. I guess the time complexity of shifting is O ( c) then. – Tobi Alafin Dec 29, 2016 at 15:41

WebApr 6, 2024 · Given an array arr [] of size N, the task is to rotate the array by d position to the left. Examples: Input: arr [] = {1, 2, 3, 4, 5, 6, 7}, d = 2 Output: 3, 4, 5, 6, 7, 1, 2 Explanation: If the array is rotated by 1 position to the left, it becomes {2, 3, 4, 5, 6, 7, 1}. When it is rotated further by 1 position, it becomes: {3, 4, 5, 6, 7, 1, 2}
