Given two promises <code>promise1</code> and <code>promise2</code>, return a new promise. <code>promise1</code> and <code>promise2</code> will both resolve with a number. The returned promise should resolve with the sum of the two numbers.

<p><strong class="example">Example 1:</strong></p>
 | 
			
		||||
 | 
			
		||||
<pre>
 | 
			
		||||
<strong>Input:</strong> 
 | 
			
		||||
promise1 = new Promise(resolve => setTimeout(() => resolve(2), 20)), 
 | 
			
		||||
promise2 = new Promise(resolve => setTimeout(() => resolve(5), 60))
 | 
			
		||||
<strong>Output:</strong> 7
 | 
			
		||||
<strong>Explanation:</strong> The two input promises resolve with the values of 2 and 5 respectively. The returned promise should resolve with a value of 2 + 5 = 7. The time the returned promise resolves is not judged for this problem.

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

 | 
			
		||||
<pre>
 | 
			
		||||
<strong>Input:</strong> 
 | 
			
		||||
promise1 = new Promise(resolve => setTimeout(() => resolve(10), 50)), 
 | 
			
		||||
promise2 = new Promise(resolve => setTimeout(() => resolve(-12), 30))
 | 
			
		||||
<strong>Output:</strong> -2
 | 
			
		||||
<strong>Explanation:</strong> The two input promises resolve with the values of 10 and -12 respectively. The returned promise should resolve with a value of 10 + -12 = -2.
