To load or not to load
All submissions for this problem are available.
Due to rapid expansion, Grofers wants to build a large distributed storage system on the web. Millions of users will store terabytes of data on its servers.
One way to design such a large system would be to hash each user’s login id, partition the hash ranges into equal sized buckets, and store the data for each bucket of users on a single server For this scheme, mapping a user to a server is a simple hash computation. However, if a small number of users occupy a large fraction of the storage space, hashing will not achieve a balanced partition. One way to solve this problem is to make the hash buckets have non uniform width based on the load in that hash range.
You have n users and m servers.
- User i requires B(i) units of storage space. You design a strategy which finds numbers K(1) through K(m) such that all users between K(j) and K(j+1) get assigned to server j.
- Your strategy minimizes the load on the most heavily loaded server. Given the array B, number of servers m and number of users n,
- your program should output the Load on the most heavily loaded server.
The first line of input is two integer value , the total number of User N, total number of Server M and the second line has space separated integers which are the user storage requirements .
Output single lines, the load on the most heavily loaded server
- 1 ≤ N ≤ 100000
- 1 ≤ M ≤ 100000
Input: 5 2 2 3 1 5 1 Output: 6
[2 3 1 5 1] so starting three user will be served by first system and last three user will be served by last server.
