and then sorts the results.

Answer 1

Please refer to the screenshot of the code to understand the indentation of the script and output

Powershell Script

#declare i variable
$i=0
#declare array number to store command line arguments
$number=@()
#declare array to store reversed digits
$reversednumber=@()
#declare variable reversed
$reversed=0
#declare variable digit
$digit=0

#for loop to store arguments in the array number
for($i=0;$i -lt 6;$i++)
{
#store each argument in an array
$number+=$args[$i]
}
#for loop to reverse digit in each arguments
for($i=0;$i -lt 6;$i++)
{
#store by index in num variable
$num=$number[$i]
# while loop runs untill num is not equal to 0
while($num -ne 0)
{
#% modulos operator to find the remainder   
[int]$digit = $num % 10
#multiply reversed by 10 and digit
[int]$reversed = ($reversed *10) + $digit
#divide the number by 10
#Math floor function is used as division in powershell return nearest whole number
[int]$num=([Math]::Floor($num/10))
}
#add the reversed number to reversednumber array
$reversednumber+=$reversed
#again intialize reversed to 0
$reversed=0
}
#used sort to sort the array in ascending and prints here
$reversednumber|sort
