"content": "<p>Alice is a caretaker of <code>n</code> gardens and she wants to plant flowers to maximize the total beauty of all her gardens.</p>\n\n<p>You are given a <strong>0-indexed</strong> integer array <code>flowers</code> of size <code>n</code>, where <code>flowers[i]</code> is the number of flowers already planted in the <code>i<sup>th</sup></code> garden. Flowers that are already planted <strong>cannot</strong> be removed. You are then given another integer <code>newFlowers</code>, which is the <strong>maximum</strong> number of flowers that Alice can additionally plant. You are also given the integers <code>target</code>, <code>full</code>, and <code>partial</code>.</p>\n\n<p>A garden is considered <strong>complete</strong> if it has <strong>at least</strong> <code>target</code> flowers. The <strong>total beauty</strong> of the gardens is then determined as the <strong>sum</strong> of the following:</p>\n\n<ul>\n\t<li>The number of <strong>complete</strong> gardens multiplied by <code>full</code>.</li>\n\t<li>The <strong>minimum</strong> number of flowers in any of the <strong>incomplete</strong> gardens multiplied by <code>partial</code>. If there are no incomplete gardens, then this value will be <code>0</code>.</li>\n</ul>\n\n<p>Return <em>the <strong>maximum</strong> total beauty that Alice can obtain after planting at most </em><code>newFlowers</code><em> flowers.</em></p>\n\n<p> </p>\n<p><strong class=\"example\">Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> flowers = [1,3,1,1], newFlowers = 7, target = 6, full = 12, partial = 1\n<strong>Output:</strong> 14\n<strong>Explanation:</strong> Alice can plant\n- 2 flowers in the 0<sup>th</sup> garden\n- 3 flowers in the 1<sup>st</sup> garden\n- 1 flower in the 2<sup>nd</sup> garden\n- 1 flower in the 3<sup>rd</sup> garden\nThe gardens will then be [3,6,2,2]. She planted a total of 2 + 3 + 1 + 1 = 7 flowers.\nThere is 1 garden that is complete.\nThe minimum number of flowers in the incomplete gardens is 2.\nThus, the total beauty is 1 * 12 + 2 * 1 = 12 + 2 = 14.\nNo other way of planting flowers can obtain a total beauty higher than 14.\n</pre>\n\n<p><strong class=\"example\">Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> flowers = [2,4,5,3], newFlowers = 10, target = 5, full = 2, partial = 6\n<strong>Output:</strong> 30\n<strong>Explanation:</strong> Alice can plant\n- 3 flowers in the 0<sup>th</sup> garden\n- 0 flowers in the 1<sup>st</sup> garden\n- 0 flowers in the 2<sup>nd</sup> garden\n- 2 flowers in the 3<sup>rd</sup> garden\nThe gardens will then be [5,4,5,5]. She planted a total of 3 + 0 + 0 + 2 = 5 flowers.\nThere are 3 gardens that are complete.\nThe minimum number of flowers in the incomplete gardens is 4.\nThus, the total beauty is 3 * 2 + 4 * 6 = 6 + 24 = 30.\nNo other way of planting flowers can obtain a total beauty higher than 30.\nNote that Alice could make all the gardens complete but in this case, she would obtain a lower total beauty.\n</pre>\n\n<p> </p>\n<p><strong>Constraints:</strong></p>\n\n<ul>\n\t<li><code>1 <= flowers.length <= 10<sup>5</sup></code></li>\n\t<li><code>1 <= flowers[i], target <= 10<sup>5</sup></code></li>\n\t<li><code>1 <= newFlowers <= 10<sup>10</sup></code></li>\n\t<li><code>1 <= full, partial <= 10<sup>5</sup></code></li>\n</ul>\n",
