编写一个函数来查找字符串数组中的最长公共前缀。
如果不存在公共前缀,返回空字符串 ""。
""
示例 1:
输入:strs = ["flower","flow","flight"] 输出:"fl"
示例 2:
输入:strs = ["dog","racecar","car"] 输出:"" 解释:输入不存在公共前缀。
提示:
1 <= strs.length <= 200
0 <= strs[i].length <= 200
strs[i]
kotlin
class Solution { fun longestCommonPrefix(strings: Array<String>): String = strings.reduce { acc, s -> acc.commonPrefixWith(s) } }
