Why using %N with rear and front increment pointer?
Why using %N with rear and front increment pointer?
Because you have to implement a circular queue.
Say array size is 4. If you want to mimic it as a circular array you will have to use %N
Say if last element in the array is at arr[3]. If you want to push an element in it… you will push it at index [(3+1)%4] which is arr[0]
