<p><strong>示例 1:</strong></p>
 | 
						||
 | 
						||
<pre><strong>输入:</strong>n = 234
 | 
						||
<strong>输出:</strong>15 
 | 
						||
<strong>解释:</strong>
 | 
						||
各位数之积 = 2 * 3 * 4 = 24 
 | 
						||
各位数之和 = 2 + 3 + 4 = 9 
 | 
						||
结果 = 24 - 9 = 15
 | 
						||
</pre>
 | 
						||
 | 
						||
<p><strong>示例 2:</strong></p>
 | 
						||
 | 
						||
<pre><strong>输入:</strong>n = 4421
 | 
						||
<strong>输出:</strong>21
 | 
						||
<strong>解释: 
 | 
						||
</strong>各位数之积 = 4 * 4 * 2 * 1 = 32 
 | 
						||
各位数之和 = 4 + 4 + 2 + 1 = 11 
 | 
						||
结果 = 32 - 11 = 21
 | 
						||
</pre>
