For faster access, operating systems (OS) divide the HDD into clusters of the size 512Bytes up to 64KB. Thus, OS can search files faster. But larger cluster size is more space wasted, thus, usually 4096Bytes (4KB) space is used.

If a file is smaller than the cluster size, the rest of the cluster is left empty, and the next file starts from the next cluster. For example, if the file's 10000Bytes and cluster size is 4096, then it will fit into 3 clusters (12 KiloBytes). And, the next file starts from the 4th cluster.

Question:
Write a program that is going to read several file information. Then, it's going to calculate the total size (in KB) occupied on HDD.
Note:

• 1KB=1024Bytes.
• You can use ceil function to calculate the number of clusters needed for the active file.

Input specification
You will be first given 2 integer numbers (n and clusterSize in KB) where 0 ≤ n ≤ 10000 and 1 ≤ clusterSize ≤ 64. Then the following n lines will give n file sizes (in Bytes) where each of the file size is between 0 and 10¹⁰.

Output specification
Show the total space occupied by all files.
(The_number_of_cluster x Cluster_size)
