特殊两位数-yiteyi-C++库

一个特殊的两位数是这样一个数字，当该数字的位数之和加上其位数的乘积时，结果等于原来的两位数。 例如：

null

input : 59.output : 59 is a Special Two-Digit NumberExplanation:Sum of digits = 5 + 9 = 14Product of its digits = 5 x 9 = 45Sum of the sum of digits and product of digits = 14 + 45 = 59input: 29output: 29 is a Special Two-digit NumberExplanation:Sum of digits = 9 + 2 = 11Product of digits = 9 * 2 = 18Sum of the sum of digits and product of digits = 11 + 18 = 29

推荐：请尝试你的方法 {IDE} 首先，在进入解决方案之前。

方法： 提取数字的第一个和最后一个数字，分别相加和相乘。然后，将两位数的和和与乘积相加，并将其与原始数字进行比较。如果它们是相同的，那么它是一个特殊的两位数，否则就不是。以下是上述方法的实施情况：
