Question- Need solution in Java Something related to IPO offering main gist is we had shares - lets say N which we want to divide among bidders Bidders are represented in 2d arrays as [bidder_id, no of shares_bid, price, timestamp] Now build a function returns the bidder_id's in sorted array that did not receive any shares.   Shares are allocated following rules-   if the price is highest among all the bidders. Allocate shares If the price is same among 2 bidders. Allocate share in iterative fashion, first one get share had earlier timestamp. Like 2 bidders with bidder id 1&2, have same price, timestamp 4 and 1, bids for 5 shares each and N=1. So, in this case only bidder id 1 get share, bidder id 2 will not recieve any shares

Question- Need solution in Java
Something related to IPO offering
main gist is we had shares - lets say N which we want to divide among bidders
Bidders are represented in 2d arrays as
[bidder_id, no of shares_bid, price, timestamp]
Now build a function returns the bidder_id's in sorted array that did not receive any shares.

 

Shares are allocated following rules-

 

  1. if the price is highest among all the bidders. Allocate shares
  2. If the price is same among 2 bidders. Allocate share in iterative fashion, first one get share had earlier timestamp.
    Like 2 bidders with bidder id 1&2, have same price, timestamp 4 and 1, bids for 5 shares each and N=1.
    So, in this case only bidder id 1 get share, bidder id 2 will not recieve any shares
