"content": "<p>An image is represented by an <code>m x n</code> integer grid <code>image</code> where <code>image[i][j]</code> represents the pixel value of the image.</p>\n\n<p>You are also given three integers <code>sr</code>, <code>sc</code>, and <code>newColor</code>. You should perform a <strong>flood fill</strong> on the image starting from the pixel <code>image[sr][sc]</code>.</p>\n\n<p>To perform a <strong>flood fill</strong>, consider the starting pixel, plus any pixels connected <strong>4-directionally</strong> to the starting pixel of the same color as the starting pixel, plus any pixels connected <strong>4-directionally</strong> to those pixels (also with the same color), and so on. Replace the color of all of the aforementioned pixels with <code>newColor</code>.</p>\n\n<p>Return <em>the modified image after performing the flood fill</em>.</p>\n\n<p> </p>\n<p><strong>Example 1:</strong></p>\n<img alt=\"\" src=\"https://assets.leetcode.com/uploads/2021/06/01/flood1-grid.jpg\" style=\"width: 613px; height: 253px;\" />\n<pre>\n<strong>Input:</strong> image = [[1,1,1],[1,1,0],[1,0,1]], sr = 1, sc = 1, newColor = 2\n<strong>Output:</strong> [[2,2,2],[2,2,0],[2,0,1]]\n<strong>Explanation:</strong> From the center of the image with position (sr, sc) = (1, 1) (i.e., the red pixel), all pixels connected by a path of the same color as the starting pixel (i.e., the blue pixels) are colored with the new color.\nNote the bottom corner is not colored 2, because it is not 4-directionally connected to the starting pixel.\n</pre>\n\n<p><strong>Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> image = [[0,0,0],[0,0,0]], sr = 0, sc = 0, newColor = 2\n<strong>Output:</strong> [[2,2,2],[2,2,2]]\n</pre>\n\n<p> </p>\n<p><strong>Constraints:</strong></p>\n\n<ul>\n\t<li><code>m == image.length</code></li>\n\t<li><code>n == image[i].length</code></li>\n\t<li><code>1 <= m, n <= 50</code></li>\n\t<li><code>0 <= image[i][j], newColor < 2<sup>16</sup></code></li>\n\t<li><code>0 <= sr < m</code></li>\n\t<li><code>0 <= sc < n</code></li>\n</ul>\n",
