求s=a+a aa+aaaa+aa...a的值，其中a是一个数字。例如2+22+222+2222+22222(此时共有5个数相加)，几个数相加有键盘控制。
1.程序分析：关键是计算出每一项的值。
-S = a+aa+aaa+aaaa+aa ... a required value, wherein a is a number. For example 2+22+222+2222+22222 (In this case the number of the sum total of five), there are a few numbers together keyboard control. 1 Program Analysis: The key is to calculate the value of each item.
