That returns a object with a Lines property. The HackerRank solution needed just the integer.
PowerShell 3.0’s cmdlet model is a hidden weapon on HackerRank. While others write 15 lines of loops, you can solve the same problem in 5 lines of clean, readable, functional pipelines.
By default, cmdlets print a standard table with preset columns.

If no employee has >=2 years experience, Where-Object outputs $null , and the rest of the pipeline should fail gracefully. HackerRank expects:
# Read input $lines = @($input) $a = $lines[0].Trim() -split ' ' | ForEach-Object [int]$_ $b = $lines[1].Trim() -split ' ' | ForEach-Object [int]$_
$lines = @($input) $n = [int]$lines[0] $arr = $lines[1].Trim() -split ' ' | ForEach-Object [int]$_
