## Problem – 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 {
public:
int rob(vector<int>& A, int i = 0) {
return i < size(A) ? max(rob(A, i+1), A[i] + rob(A, i+2)) : 0;
}
};
```

### House Robber LeetCode Solution in Python

```
class Solution:
def rob(self, A, i = 0):
return max(self.rob(A, i+1), A[i] + self.rob(A, i+2)) if i < len(A) else 0
```

### House Robber LeetCode Solution in Java

```
public int rob(int[] num) {
int[][] dp = new int[num.length + 1][2];
for (int i = 1; i <= num.length; i++) {
dp[i][0] = Math.max(dp[i - 1][0], dp[i - 1][1]);
dp[i][1] = num[i - 1] + dp[i - 1][0];
}
return Math.max(dp[num.length][0], dp[num.length][1]);
}
```
