Cant understand the question

#1

Hi @vmayaan,
According to the question,

  • Initially there are N students and M coupons
  • 100% wavier is given to those who have at least X coupons (good students)
  • Bad students must give Y coupons to take admission

So, let’s form an equation, If there are k good students then (N - k) students must have performed bad.

Initial Coupons - k*X + (N - k)*Y >= 0
Initial Coupons = M

You, just need to solve this equation by maximizing k such that k <= N

Hint: You can apply binary search for optimal k
