<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>

<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>

<p>Return <code>true</code><em> if <strong>all</strong> asteroids can be destroyed. Otherwise, return </em><code>false</code><em>.</em></p>

<p><strong class="example">Example 1:</strong></p>

<pre>
<strong>Input:</strong> mass = 10, asteroids = [3,9,19,5,21]
<strong>Output:</strong> true
<strong>Explanation:</strong> One way to order the asteroids is [9,19,5,3,21]:
- The planet collides with the asteroid with a mass of 9. New planet mass: 10 + 9 = 19
- The planet collides with the asteroid with a mass of 19. New planet mass: 19 + 19 = 38
- The planet collides with the asteroid with a mass of 5. New planet mass: 38 + 5 = 43
- The planet collides with the asteroid with a mass of 3. New planet mass: 43 + 3 = 46
- The planet collides with the asteroid with a mass of 21. New planet mass: 46 + 21 = 67
All asteroids are destroyed.
</pre>

<p><strong class="example">Example 2:</strong></p>

<pre>
<strong>Input:</strong> mass = 5, asteroids = [4,9,23,4]
<strong>Output:</strong> false
<strong>Explanation:</strong> 
The planet cannot ever gain enough mass to destroy the asteroid with a mass of 23.
After the planet destroys the other asteroids, it will have a mass of 5 + 4 + 9 + 4 = 22.
This is less than 23, so a collision would not destroy the last asteroid.</pre>
