- I'm going to be away the next couple weeks, but here's an approach in J.
- Using the following input:
Employees=: (<;.1~ (#{.,~@:1:);+./@:(;: E.S:0 ])@:{.) ];._2 noun define EMP_NAME EMP_ID HIRE_DATE SALARY DEPT EXEMPT INTERESTS Tyler Bennett E10297 19770601 32000 D101 Y John Rappl E21437 19870715 47000 D050 Y 1 George Woltman E00127 19820807 53500 D101 Y 2 Adam Smith E63535 19880115 18000 D202 N Claire Buckman E39876 19851123 27800 D202 Y David McClellan E04242 19820727 41500 D101 Y 3 Rich Holcomb E01234 19830601 49500 D202 Y Nathan Adams E41298 19880215 21900 D050 N Richard Potter E43128 19860412 15900 D101 N David Motsinger E27002 19850505 19250 D202 N Tim Sampair E03033 19871202 27000 D101 Y Kim Arlich E10001 19850730 57000 D190 Y Timothy Grove E16398 19850121 29900 D190 Y )
- The top earners in each dept are:
('`',,;:^:_1:N=:{.Employees) =: , (_&{"1)`'' ([^:(_ -: ])L:0)"0 _~ i.# E=:{:Employees
N , (<@:>"1@:|:@:((6 <. #) {. ] \: SALARY)/.~ DEPT) |: <"1&> E
