Parameters:

value - word to calculate variations

Returns:

number of variations.

indexOfNextCaseSensitiveCharacter

public static OptionalInt indexOfNextCaseSensitiveCharacter(CharSequence text,
                                                            int startIndex)

Parameters:

text - text to be analyzed

startIndex - start search from index.

Returns:

index of next case sensitive character or empty if no such character present
