+```java
+public class Solution {
+    public int rob(int[] nums) {
+        if (nums.length == 1) {
+            return nums[0];
+        }
+
+        if (nums.length == 2) {
+            return Math.max(nums[0], nums[1]);
+        }
+
+        if (nums.length == 3) {
+            return Math.max(nums[2], Math.max(nums[0], nums[1]));
+        }
+
+
+        return Math.max(getMaxInRange(nums, 0, nums.length - 1), getMaxInRange(nums, 1, nums.length));
+    }
+
+    public int getMaxInRange(int[] nums, int start, int end) {
+        int[] dp = new int[nums.length];
+        int max;
+        dp[start] = nums[start];
+        dp[start + 1] = nums[start + 1];
+        dp[start + 2] = nums[start + 2] + nums[start];
+        max = Math.max(dp[start + 2], dp[start + 1]);
+        for (int i = start + 3; i < end; i++) {
+            dp[i] = Math.max(nums[i] + dp[i - 2], nums[i] + dp[i - 3]);
+            max = Math.max(max, dp[i]);
