Problem- A sample of starch is hydrolyzed for some unknown length of time. It gives a negative iodine test and a negative Benedict's test. How hydrolyzed is this sample (in terms of the fragment size or number of glucose units still connected)?

I want to know how this is done please show all steps in detail
