extends java.lang.Object
522 - Longest Uncommon Subsequence II.
Medium
Given an array of strings strs
, return the length of the longest uncommon subsequence between them. If the longest uncommon subsequence does not exist, return -1
.
An uncommon subsequence between an array of strings is a string that is a subsequence of one string but not the others.
A subsequence of a string s
is a string that can be obtained after deleting any number of characters from s
.
- For example,
"abc"
is a subsequence of"aebdc"
because you can delete the underlined characters in"aebdc"
to get"abc"
. Other subsequences of"aebdc"
include"aebdc"
,"aeb"
, and""
(empty string).
Example 1:
Input: strs = [“aba”,“cdc”,“eae”]
Output: 3
Example 2:
Input: strs = [“aaa”,“aaa”,“aa”]
Output: -1
Constraints:
2 <= strs.length <= 50
1 <= strs[i].length <= 10
strs[i]
consists of lowercase English letters.
