Given a list of float numbers, and four operators +, -, *, / with flat preference, 
find the maximum value by inserting operator between each consecutive pair of numbers.

For example, given the array [1, 12, -3], the maximum number 33 can be found using 
1 - 12 * (-3), since all operators have flat preference, so 1 - 12 * (-3) will be 
handled from left to right, first operation is 1 - 12 with value -11, and then second 
operation is -11 * (-3) = 33.
    
Peer's analysis and code:

    arr.Length-1 
    
    float[] GetMax(float[] arr  , int len)    
    
    arr ==null || len==0 :- return 0;
    if len==1 return arr[0];

    float[] next = GetMax(arr, len-1);

    float max = Double.MinValue;
    float max = Double.MinValue;

    max = Math.Max(max, next + arr[len]);
    max = Math.Max(max, next - arr[len]);
    max = Math.Max(max, next * arr[len]); // 1 - 12 
    max = Math.Max(max, next / arr[len]);
    return max;
