    public class Solution {
        public int maxProduct(int[] nums) {
            int Max = 1;
            int Min = 1;
            int ans = Integer.MIN_VALUE;
            for (int k=0; k<nums.length; k++){
                int newMax = Math.max(Math.max(nums[k]*Max, nums[k]*Min),nums[k]);
                int newMin = Math.min(Math.min(nums[k]*Max, nums[k]*Min),nums[k]);
                ans = Math.max(ans, newMax);
                Max = newMax;
                Min = newMin;
            }
            return ans;
        }
    }
    

    Why this solution is not as efficient as other solutions shared here? I think my solution also takes O(N) time. Any suggestions to improve it?
