I am not able to understand the ‘size of circle’ thing, can anyone please make me understand

# Not able to understand 'size of circle'' thing

Think of it like, there are B locations numbered from 1 to B, they are located on a circle. So when you start from a location numbered C, you need to deliver A packages to these locations in circular order. Note: You should also deliver to the location C. All you need to find is the location where you will deliver the last package.

Here size of circle means no. of children/student sitting in a circular way. Suppose B=5 then 5 no. of students sitting in circular way i.e ‘the size of the circle is 5’.
