Is this a homework assignment? Homework and coursework questions can only be posted in this forum in a particular format described in special homework rules.

If this is homework, please repost it in the Homework & Coursework forum in the required format.

If not, please show us a sample of your input. Does it come from a file, is data manually entered, or what is the source? What is the format of the input data? Is it a CSV file using the pipe symbol as the field separator or is it some other format? Is there a heading line in the input?

Exactly what output you are trying to produce from your sample intermediate output (with the percentages you said you want, but did not describe).

What is your definition of a "blank space"? Is it an empty string? Is it a single <space> character? Is it a single character in the current locale's blank character class? Is it a string of one or more <space> characters? Is it a string of one or more characters in the current locale's blank character class? Is it a string of zero or more <space> characters? Is it a string of zero or more characters in the current locale's blank character class?

Please explain the logic used to determine when the output should be TRUE or FALSE and the logic used to determine when the output should be Positive or Negative.

If blank space is an empty string or a single <space>, why isn't the line in your intermediate output:

Code:

<BLANK>|<BLANK>|True Negative

be:

Code:

<BLANK>|<BLANK>|True Positive

instead. Shouldn't identical strings be Positive???

If blank space is a single <space> character, why isn't the line your intermediate output:

Code:

Binny's Sales|<BLANK>|False Negative

be:

Code:

Binny's Sales|<BLANK>|True Positive

instead. Shouldn't the <space> in the second field be considered a substring of the 1st field (matching the space in the middle of the 1st field?

What operating system and shell are you using?

What have you tried to solve this problem on your own?
