(Easy) House Robber LeetCode

class Solution {
    public int rob(int[] nums) {

        if(nums.length<=0 || nums ==null){
            return 0;
        }

        if( nums.length ==1){
            return nums[0];
        }

        if(nums.length ==2){

            return Max(nums[0],nums[1]);
        }

        int[] dp = new int[nums.length];

        dp[0] = nums[0];
        dp[1] = Max(nums[0],nums[1]);

        for(int i = 2; i<nums.length; i++){

            dp[i] = Max((dp[i-2]+nums[i]),dp[i-1]);
        }

        return dp[nums.length-1];
    }

    public int Max(int a, int b){

        return a>b? a: b;
    }
}
