An institute runs batches training students in C#. A new batch starts on the 1st of every month and every batch lasts for exactly 3 months (thus at any given time, the students of exactly 3 batches will be present concurrently). The table below gives the information for the total number of students studying at the institute in each month of 2018 (some values have intentionally been left blank).
It is also known that 95 new students joined in May, while 91 new students joined in September.
Find out how many joined when and how many left when ? Please share your approach.
you can use the structure like Month|total students| New joinee |leaving student
