Joey is at Central Perk Cafe drinking coffee. He has decided to order n litres of coffee.
Central Perk offers coffee in mugs. Each mug can hold k litres of coffee.
Find the minimum number of coffee mugs needed by Central Perk to fill n litres of coffee.
See the sample case for better understanding.
Input format:
One line containing two integers n and k.
Output format:
Print the minimum number of mugs needed by Central Perk.
Constraints:
0 <= n <= 1000000000 (10^9)
1 <= k <= 1000000000 (10^9)
We need to fill 9 litres of coffee in mugs.
As each mug can hold 3 litres of coffee, we can have 3 mugs each filled with 3 litres of coffee.
Hence, minimum required mugs are 3.
