hello,

I new perl learner, so forgive me if my question seemed basic.

I need a perl script to look up the unique elements in array and sum the corresponding values. let me make it clear

here is how my input file will look like: 
AA 12
bb 34
AA 76
cc 98
dd 76
bb 98

[download]
Note: the file is tab delimited

I need the script to give me the following output:

AA 88
bb 132
cc 98
dd 76

[download]
the input is like a table of two columns or more. I don't why it appeared as a line in my question even thought I entered it as table. so basically the first column contain (AA, bb, AA, cc, dd, bb) and the second column contain (12, 34, 76, 98, 76, 98)

Can anyone help me with writing this script?
