I have a text file of 20 or so strings, ranging from one character to about a 20 character long string. some of them are numbers, some are alphabetical and some are special characters. none of them are mixed character types.
I want to create a text file from these strings that contains every combination of each string.
the special character strings need to be used in both forward and reverse, the numbers= strings in forward and reverse, and the alphabetical strings need to be used in lower case, upper case, and both ways of alternating capitals in the string.
ie. StRiNg and sTrInG

for each possible mutation of each string they need to be concatenated in every possible combination,
ie var1,var2,var3,var(n) including just two strings up to all 20 strings
