无语了 阅读理解有问题 没读明白题 脑经急转弯

java：

class Solution {
    public int findLUSlength(String a, String b) {
        int n = 0;
        if (a.equals(b)){
            n = -1;
        }else {
            n = Math.max(a.length(), b.length());
        }
        return n;
    }
}

python3:

class Solution:
    def findLUSlength(self, a: str, b: str) -> int:
        if a != b:
            return max(len(a), len(b))
        else:
            return -1
