In this code, the overlapping nested loop is the root of the problem, causing the output to print each line twice.

Solution

To resolve this issue and achieve the desired output without duplication, we will make a few simple adjustments in the processfile() function.

Clean Up the Code

Remove the Nested Loop: The first loop is already iterating through the array, so there's no need for a second loop to do the same.

Directly Use the Array: We can simplify the logic to directly log the contents.

Explanation of Changes

Simplification: By removing the unnecessary second loop, we ensure each line is printed only once.
