+198. House Robber
+Difficulty: Medium
+https://leetcode.com/problems/house-robber/
+
+──────────────────────────────────────────────────
+
+You are a professional robber planning to rob houses along a street.
+Each house has a certain amount of money stashed, the only constraint
+stopping you from robbing each of them is that adjacent houses have
+security systems connected and it will automatically contact the
+police if two adjacent houses were broken into on the same night.
+
+Given an integer array nums representing the amount of money of each
+house, return the maximum amount of money you can rob tonight without
+alerting the police.
+
+
+
+Example 1:
+
+Input: nums = [1,2,3,1]
+Output: 4
+Explanation: Rob house 1 (money = 1) and then rob house 3 (money = 3).
+Total amount you can rob = 1 + 3 = 4.
+
+Example 2:
+
+Input: nums = [2,7,9,3,1]
+Output: 12
+Explanation: Rob house 1 (money = 2), rob house 3 (money = 9) and rob
+house 5 (money = 1).
+Total amount you can rob = 2 + 9 + 1 = 12.
+
+
+
+Constraints:
+
+        • 1 <= nums.length <= 100
+
+        • 0 <= nums[i] <= 400

+class Solution:
+    def rob(self, nums: list[int]) -> int:
+        n = len(nums)
+        if n == 0:
+            return 0
+        if n <= 2:
+            return max(nums)
+
+        dp = [0] * n
+        dp[0] = nums[0]
+        dp[1] = max(nums[0], nums[1])
+        for i in range(2, n):
+            dp[i] = max(dp[i - 1], dp[i - 2] + nums[i])
+        return dp[-1]
