Hence, with change of coordinate from P ( h, k) to P ( k, - h) we can rotation a figure 90 clockwise about a point. Let's understand the rotation of 90 degrees clockwise about a point visually. You have to modify the input matrix in-place. Since, 270 degree clockwise rotation 90 degree counterclockwise rotation, both the movements will result in same final coordinate. Expected Time Complexity: O (N2) Expected Auxiliary Space: O (1) Constraints: 1 N. Let us look at solved examples for better understanding of the concept. Example 01 The point (3, 1) is rotated by 270 degrees in clockwise direction. Matrix after rotating 90 degree clockwise: 65 45 25 5 70 50 30 10 75 55 35 15 80 60 40 20 Explanation for Anticlockwise rotation: A given N x N matrix will have (N/2) square cycles. I am using an Asus T100HA with the Teams application for meetings. Note that the id of the canvas is the same. When a point say P ( h, k) is rotated about origin O through 90 ° clockwise direction, the new position will be P ( k, - h) Since to rotate 90 ° clockwise about a point, every point x, y will rotate to y, - x. If I try to switch on Video my image is rotated 90 degrees clockwise and I cannot find anywhere to adjust the settings. Hence, with change of coordinate from P ( h, k) to P ( k, - h) we can rotation a figure 90 ° clockwise about a point. Other things to note: Webcam is fine in Skype (Microsoft App) Webcam is find in Camera (Microsoft App) Webcam is fine with Zoom. Imagine simply rotating an image clockwise without it being cropped or being padded.
