HackerRank judges don't care about micro-optimizations; they care about correctness. Cmdlet pipelines reduce bugs. Get-Content reads the file line-by-line

HackerRank expects the final output to match a specific string format. Often, you may need to join array elements into a single string using the operator or use Out-String Review & Best Practices Use Full Names, Not Aliases : In a "review" context or for shared scripts, avoid using Where-Object ForEach-Object .
