PROBLEM:

Chef has bought a New Bike for Himself and he is going for a long trip on his new bike. Chef’s New bike gives the average of 1km per Liter.

The capacity of tank of his bike is 10 Liters.
You are given an integers N i.e Total number of kilometre he want to travel in his long trip

Print the total number of time chef needs to refuel his tank to reach his destination.

QUICK EXPLANATION:

As we know that the bike gives the average to 1km per/liter. and the capacity of the bike tank is 10 liters. so in a single refuel the bike will cover the distance of 10km.

So we can print the answer by (total number of kilometres / 10) This formula will apply only for the total kilometres which are multiple of 10. For the total number of kilometres which are not multiple of 10. we can print the answer by ((total number of kilometres / 10)+1).
