📝 Problem Description
You are given an $N \times N$ matrix (2D vector). You need to perform a series of operations in a specific order to transform the matrix.
Operations:
- Rotation: Rotate the matrix clockwise by a given angle $\theta \in \{90^\circ, 180^\circ, 270^\circ\}$.
- Vertical Flip: If
vertical_flip == 1, flip the matrix vertically (up-to-down). - Horizontal Flip: If
horizontal_flip == 1, flip the matrix horizontally (left-to-right).
Input Format:
- A 2D vector
matrix. - An integer
angle(90, 180, or 270). - An integer
v_flip(0 or 1). - An integer
h_flip(0 or 1).
