I am doing a time caclulation where i have output data with "Enter" & "Exit" time. I need to basically do a mathematical operation.
Following is the output file format
output.txt
==================
What to do:
------------
The line starting with "L" has exit time in 2rd column & line starting with "E" has "start" time in 2nd column after colon ":".
I need to get output fwith "leave time" minus(-) "start time" i.e subtraction.
This has to be done for every "enter" , "exit" pair in above file. eg. for first 2 lines execution time will be 928079-927629 = 530 and so on
Please guide.

With your sample input, it produces the output:
