Hello Monks,

GoodEvening

Can any one help me on this, How this can be done in perl

Thank you very much in advance

I have 4 different Scenarios, I have listed down, and i have also written how my hash should store

STRUCTURE OF MY DATA below(with Header, last two fields are date fields in yyyymmdd format):

A1,B1,ACTDATE,DEACTDATE

7900724666,200906888,20180406,20180411

7900724666,200906888,20180416,20180522

7900724666,200906888,20180601,20180720

For the above content(A1), i want to store in hash like this==>A1,B1 of MIN ACTDATE:B1 of MAX DEACTDATE,MIN ACTDATE,MAX DEACTDATE

For the above example, ==>7900724666,200906888:200906888,20180406,20180720

7900724677,200906871,20180101,20180228

7900724677,200906872,20180301,20180330

7900724677,200906873,20180401,20180420

For the above content(A1), i want to store in hash like this==>7900724677,200906871:200906873,20180101,20180420

7900724688,200906881,20180101,20180228

7900724688,200906881,20180303,20180330

7900724688,200906882,20180404,20180430

7900724688,200906883,20180508,20180620

For the above content(A1), i want to store in hash like this==>7900724688,200906881:200906883,20180101,20180620

7900724699,200906891,20180101,20180228

7900724699,200906891,20180303,20180330

7900724699,200906892,20180404,20180430

7900724699,200906893,20180508,

For the above content(A1), i want to store in hash like this==>7900724699,200906891:NULL,20180101,NULL
