I'm stuck on the following question part b:
I got one reason down since the algorithm doesn't give a specific output, it doesn't have a line which tells you to print the number. However for the second reason it talks about the cube root being in an interval like this:
'Need to know an interval within which the cube root lies at the outset'
'Many identified the lack of output but most struggled to identify the need for an interval to be known and those who did often lacked the ability to express themselves clearly'
The algorithm finds an approximate cube root, I don't know what it means by an interval, what interval is it talking about? I didn't know there was an interval when finding a cube root, can anyone explain?
Here's the mark scheme for reference with the cube root underlined:
