"content": "<p>You are given an integer <code>mass</code>, which represents the original mass of a planet. You are further given an integer array <code>asteroids</code>, where <code>asteroids[i]</code> is the mass of the <code>i<sup>th</sup></code> asteroid.</p>\n\n<p>You can arrange for the planet to collide with the asteroids in <strong>any arbitrary order</strong>. If the mass of the planet is <b>greater than or equal to</b> the mass of the asteroid, the asteroid is <strong>destroyed</strong> and the planet <strong>gains</strong> the mass of the asteroid. Otherwise, the planet is destroyed.</p>\n\n<p>Return <code>true</code><em> if <strong>all</strong> asteroids can be destroyed. Otherwise, return </em><code>false</code><em>.</em></p>\n\n<p> </p>\n<p><strong>Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> mass = 10, asteroids = [3,9,19,5,21]\n<strong>Output:</strong> true\n<strong>Explanation:</strong> One way to order the asteroids is [9,19,5,3,21]:\n- The planet collides with the asteroid with a mass of 9. New planet mass: 10 + 9 = 19\n- The planet collides with the asteroid with a mass of 19. New planet mass: 19 + 19 = 38\n- The planet collides with the asteroid with a mass of 5. New planet mass: 38 + 5 = 43\n- The planet collides with the asteroid with a mass of 3. New planet mass: 43 + 3 = 46\n- The planet collides with the asteroid with a mass of 21. New planet mass: 46 + 21 = 67\nAll asteroids are destroyed.\n</pre>\n\n<p><strong>Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> mass = 5, asteroids = [4,9,23,4]\n<strong>Output:</strong> false\n<strong>Explanation:</strong> \nThe planet cannot ever gain enough mass to destroy the asteroid with a mass of 23.\nAfter the planet destroys the other asteroids, it will have a mass of 5 + 4 + 9 + 4 = 22.\nThis is less than 23, so a collision would not destroy the last asteroid.</pre>\n\n<p> </p>\n<p><strong>Constraints:</strong></p>\n\n<ul>\n\t<li><code>1 <= mass <= 10<sup>5</sup></code></li>\n\t<li><code>1 <= asteroids.length <= 10<sup>5</sup></code></li>\n\t<li><code>1 <= asteroids[i] <= 10<sup>5</sup></code></li>\n</ul>\n",
