function Get-HammingDistance {
<#
.SYNOPSIS
Get the Hamming Distance between two strings or two positive integers.
.DESCRIPTION
The Hamming distance between two strings of equal length is the number of positions at which the
corresponding symbols are different. In another way, it measures the minimum number of substitutions
required to change one string into the other, or the minimum number of errors that could have
transformed one string into the other. Note! Even though the original Hamming algorithm only works for
strings of equal length, this function supports strings of unequal length as well.
The function also calculates the Hamming distance between two positive integers (considered as binary
values); that is, it calculates the number of bit substitutions required to change one integer into
the other.
.EXAMPLE
Get-HammingDistance 'karolin' 'kathrin'
Calculate the Hamming distance between the two strings. The result is 3.
.EXAMPLE
Get-HammingDistance 'karolin' 'kathrin' -NormalizedOutput
Calculate the normalized Hamming distance between the two strings. The result is 0.571428571428571.
.EXAMPLE
Get-HammingDistance -Int1 61 -Int2 15
Calculate the hamming distance between 61 and 15. The result is 3.
