    public class Solution {
        public string OptimalDivision(int[] nums) {
            if (nums.Length==1) return nums[0].ToString();
            string str=String.Join("/",nums);
            if (nums.Length==2) return str;
            int x=str.IndexOf("/");
            return str.Substring(0,x+1)+"("+str.Substring(x+1,str.Length-x-1)+")";
            
        }
    }
    

    C# code -> Idea is to minimize denominator.
    How to do this =>
    Can be achieved by
    nums[0]/(nums[1]/nums[2]...nums[n-1])
