Hi ,
I have an Array of Hashes as follows:
@array = (
{ 'A'=>1, 'B' =>2, 'C'=>3, 'D'=>4}
{ 'A'=>5, 'B' =>6, 'C'=>7, 'D'=>8}
{ 'A'=>9, 'B' =>10, 'C'=>11, 'D'=>12}
{ 'A'=>13, 'B' =>14, 'C'=>15, 'D'=>16}
{ 'A'=>17, 'B' =>18, 'C'=>19, 'D'=>20}
{ 'A'=>21, 'B' =>22, 'C'=>23, 'D'=>24}
)
I have given a reference to this array in my script.
I want to do some calculation with only one key of each hash. For
example, I want to subtract from the value of key 'B' of last hash all
the other values of the same key into a one column like follows
22-2 20
22-6 16
22-10 12
22-14 8
22-18 4
22-22 0
Can you please tell me how to do this ?
Kind regards,
Geetha
