Continuous input string, by the length of the output string array to a new resolution after each string 8; 8 is not an integer multiple of the length of a string of numbers 0 Please back up, not the empty string processing.

This problem mainly has the idea of ​​direct experience: the direction of thinking to solve the problem is more convenient

/**
 *连续输入字符串，请按长度为8拆分每个字符串后输出到新的字符串数组；
 * 长度不是8整数倍的字符串请在后面补数字0，空字符串不处理。
 * 连续输入字符串(输入2次,每个字符串长度小于100)
 * 输出到长度为8的新字符串数组
