How to get alternating characters from a string in powershell?

@giovanny.lueilwitz 

You can get alternating characters from a string in PowerShell by iterating through the characters of the string and selecting every other character. Here's an example code snippet to achieve this:

1
2
3
4
5
6

$string = "Hello World"
$alternatingCharacters = ""
for ($i = 0; $i -lt $string.Length; $i += 2) {
    $alternatingCharacters += $string[$i]
}
Write-Output $alternatingCharacters

In this code snippet, we first define the input string "Hello World". We then create an empty string variable $alternatingCharacters to store the alternating characters. We use a for loop to iterate through the characters of the input string and select every other character at index $i. Finally, we output the resulting alternating characters string.

When you run this code snippet, you will get the output "HloWrd", which consists of alternating characters from the input string "Hello World".
