Ticket Fine solution codechef

Test case 1: The total number of passengers travelling without ticket are 1 – 1 = 0. So the total fine collected is 0 \cdot 4 = 0 rupees.

Test case 2: The total number of passengers travelling without ticket are 10 – 7 = 3. So the total fine collected is 3 \cdot 2 = 6 rupees.

Test case 3: The total number of passengers travelling without ticket are 5 – 4 = 1. So the total fine collected is 1 \cdot 8 = 8 rupees.
