* @Description: TODO 力扣93题 复原IP地址：
* 有效 IP 地址 正好由四个整数（每个整数位于 0 到 255 之间组成，且不能含有前导 0），整数之间用 '.' 分隔。
* <p>
* 例如："0.1.2.201" 和 "192.168.1.1" 是 有效 IP 地址，但是 "0.011.255.245"、"192.168.1.312" 和 "192.168@1.1" 是 无效 IP 地址。
* 给定一个只包含数字的字符串 s ，用以表示一个 IP 地址，返回所有可能的有效 IP 地址，这些地址可以通过在 s 中插入 '.' 来形成。你 不能 重新排序或删除 s 中的任何数字。你可以按 任何 顺序返回答案。
* @Version: 1.0
