int uniquePathsWithObstacles(int** obstacleGrid, int obstacleGridSize,
                             int* obstacleGridColSize) {
    int n = obstacleGridSize, m = obstacleGridColSize[0];
    int f[m];
    memset(f, 0, sizeof(f));
    f[0] = (obstacleGrid[0][0] == 0);
    for (int i = 0; i < n; ++i) {
        for (int j = 0; j < m; ++j) {
            if (obstacleGrid[i][j] == 1) {
                f[j] = 0;
                continue;
            }
            if (j - 1 >= 0 && obstacleGrid[i][j - 1] == 0) {
                f[j] += f[j - 1];
            }
        }
    }

    return f[m - 1];
