Find First Fit for Solar Panel in Grid

Given a 2D grid of 0s and 1s, and a solar panel's height and width, find the first coordinate where the panel can fit. 0 means empty, 1 means blocker. Input Format The first line contains two integers n and m (1 ≤ n, m ≤ 100) representing grid rows and columns. The next n lines each contain m integers representing the grid state (0 or 1). The last line contains two integers h and w (1 ≤ h ≤ n, 1 ≤ w ≤ m) for the solar panel's height and width. Output Format Output two integers i and j if there exists a suitable starting top-left coordinate (0-based), or -1 -1 if none exists. Example Input 3 3 0 0 0 0 0 1 1 1 0 2 2 Output 0 0 Constraints Up to 20% of the grid points can be blockers. Example Input 3 3 0 0 0 0 0 1 1 1 0 2 2
