521. Longest Uncommon Subsequence I - LeetCode

Question

521. Longest Uncommon Subsequence I

Solution

題目大意：給兩個字符串，找出非共同子串的最大長度

思路：字符串相等就返回-1，不等就返回長度大的那個長度

Java實現：

public int findLUSlength(String a, String b) {
    int aLength = a.length();
    int bLength = b.length();
    if (aLength != bLength) return Math.max(aLength, bLength);
    if (a.equals(b)) return -1;
    return aLength;
}

2

public int findLUSlength(String a, String b) {
    if (a.equals(b)) return -1;
    return Math.max(a.length(), b.length());
}
