# Add defensive check $data = Import-Csv .\employees.csv | Where-Object $_.YearsOfExperience -ge 2 if (-not $data) Write-Host "No eligible employees"; exit # then continue... But if they disallow if , use Select-Object with -Skip trickery or rely on Format-Table to output nothing. CSV imports all values as strings. Convert to int before sorting:

$data = Import-Csv .\employees.csv Filters objects based on a condition. powershell 3 cmdlets hackerrank solution

$data | Select-Object *, @N="SalaryInt";E=[int]$_.Salary | Sort-Object SalaryInt -Desc Better yet, cast during filtering: # Add defensive check $data = Import-Csv

| Select-Object Department, @Name="AverageSalary"; Expression= Measure-Object Salary -Average).Average Let's assume the CSV file employees.csv looks like this: Convert to int before sorting: $data = Import-Csv

Department AverageSalary ---------- ------------- Finance 100000 IT 85000 The challenge will silently test you on: Case 1: Fewer than 3 eligible employees If only 2 employees have >=2 years experience, your Select-Object -First 3 will return just 2, and Group-Object still works fine. Case 2: One department with multiple top earners If all top 3 are from IT, grouping will show only one row for IT with average salary of those 3. Case 3: Empty dataset If no employee has >=2 years experience, Where-Object outputs $null , and the rest of the pipeline should fail gracefully. HackerRank expects:

Good luck, and may the pipeline be with you!

$avgSalary = $grouped.Group | Measure-Object Salary -Average Creates new columns on-the-fly.
