I get the s2 string from a response from a server. Instead string s1 is a value of a parameter. When I ask :. I get an 19 output which means " string s1 is lexicographically greater than the string argument s2".Bolens 21 push mower 140cc parts
Just a guess, but it's the only reason I can think of that explains what you're seeing: The two minus signs are not in fact the same character. There are several characters that look are printed similar, but they are different unicode characters. See this link for the many characters that are considered a "dash".

Your two strings are not "-7ff9"no matter how much you think they are. If both s1 and s2 actually was "-7ff9"they would indeed be equal. Try to figure out what their actual values are.

If the size of the string is greater then or equal to k then we need to replace all symbols in the suffix of first k symbols of string smallest symbols and replace the character before this suffix with next greater character existing in the string.
Note: If k — 1 index in string holds the greatest character then we move one index back and we move back until we find a character which is not equal to the greatest character.

Lexicographically Greater String

I understand that it compares corresponding characters in the string, however its unclear as to why there is more, for lack of a better term, "weight" placed on the fact that a is less than b first position in first string rather than the fact that a is less than b in the second string second position.
From the docs :. The comparison uses lexicographical ordering: first the first two items are compared, and if they differ this determines the outcome of the comparison; if they are equal, the next two items are compared, and so on, until either sequence is exhausted.
Lexicographical ordering for strings uses the Unicode code point number to order individual characters. The result False is returned as soon as a is found to be less than b.
Strings are compared lexicographically using the numeric equivalents the result of the built-in function ord of their characters. Unicode and 8-bit strings are fully interoperable in this behavior. Python and just about every other computer language use the same principles as I hope you would use when finding a word in a printed dictionary:.
Typically, in a computer language the "notion of character ordering" is rather primitive: each character has a human-language-independent number ord character and characters are compared and sorted using that number. Often that ordering is not appropriate to the human language of the user, and then you need to get into "collating", a fun topic. Take a look also at How do I sort unicode strings alphabetically in Python? Lott, there is a famous counter-example when sorting French language.
It involves accents: indeed, one could say that, in French, letters are sorted left-to-right and accents right-to-left. And a last remark: you shouldn't be talking about left-to-right and right-to-left sorting but rather about forward and backward sorting. Indeed there are languages written from right to left and if you think Arabic and Hebrew are sorted right-to-left you may be right from a graphical point of view, but you are wrong on the logical level!
Indeed, Unicode considers character strings encoded in logical orderand writing direction is a phenomenon occurring on the glyph level.Ryzen 5 2600x rx 580
To sort this word one will first consider the shin, then the lamed, then the vav, then the mem, and this is forward ordering although Hebrew is written right-to-leftwhile French accents are sorted backwards although French is written left-to-right.
This is a lexicographical ordering. It just puts things in dictionary order. This function does the equivalent of the real method Python 3. It's just to illustrate how it works.There are many times different types of sorting has been discussed in python lists.
The sorting of python list of lists has also been discussed. But sometimes, we have two parameters upon which we need to sort.
First one being the list sum and next being its length. Method 1 : Using sort twice The first approach that comes into the mind is the generic way that is to use the sort function twice, firstly on basis of the value and then on basis of size of list. The original list is : [[1, 4, 3, 2], [5, 4, 1], [1, 4, 6, 7]] The list after sorting by value and length [[5, 4, 1], [1, 4, 3, 2], [1, 4, 6, 7]].
Method 2 : Using lambda function The above method calls a single sort function twice but as an improvement to it, this method calls the sort function just once and uses lambda function to perform both sorts in one go.

Sign up or log in Sign up using Google.In mathematicsthe lexicographic or lexicographical order also known as lexical orderdictionary orderalphabetical order or lexicographic al product is a generalization of the way words are alphabetically ordered based on the alphabetical order of their component letters.
This generalization consists primarily in defining a total order on the sequences often called strings in computer science of elements of a finite totally ordered setoften called an alphabet.
There are several variants and generalizations of the lexicographical ordering. One variant widely used in combinatorics orders subsets of a given finite set by assigning a total order to the finite set, and converting subsets into increasing sequencesto which the lexicographical order is applied.
Another generalization defines an order on a Cartesian product of partially ordered sets ; this order is a total order if and only if the factors of the Cartesian product are totally ordered. The word lexicographic is derived from lexiconthe set of words that are used in some language and appear in dictionaries and encyclopedias.
The lexicographic order has thus been introduced for sorting the entries of dictionaries and encyclopedias. This has been formalized in the following way. Consider a finite set Aoften called alphabetwhich is totally ordered.
In dictionaries, this is the common alphabet, ordered by the alphabetical order. In book indexesthe alphabet is generally extended to all alphanumeric characters; it is the object of a specific convention whether a digit is considered as smaller or larger than a letter. The lexicographic order is a total order on the sequences of elements of Aoften called words on Awhich is defined as follows. Given two different sequences of the same length, a 1 a To compare sequences of different lengths, the shorter sequence is usually padded at the end with enough "blanks" a special symbol that is treated as smaller than every element of A.
This way of comparing sequences of different lengths is always used in dictionaries. However, in combinatoricsanother convention is frequently used, whereby a shorter sequence is always smaller than a longer sequence.
This variant of the lexicographical order is sometimes called shortlex order. In dictionary order, the word "Thomas" appears before "Thompson" because the letter 'a' comes before the letter 'p' in the alphabet. The 5th letter is the first that is different in the two words; the first four letters are "Thom" in both. Because it is the first difference, the 5th letter is the most significant difference for the alphabetical ordering. An important property of the lexicographical order on words of a fixed length on a finite alphabet is that it is a well-order ; that is, every decreasing sequence of words is finite.
The lexicographical order is used not only in dictionaries, but also commonly for numbers and dates. One of the drawbacks of the Roman numeral system is that it is not always immediately obvious which of two numbers is the smaller. On the other hand, with the positional notation of the Hindu—Arabic numeral systemcomparing numbers is easy, because the natural order on nonnegative integers is the same as the variant shortlex of the lexicographic order.
In fact, with positional notation, a nonnegative integer is represented by a sequence of numerical digitsand an integer is larger than another one if either it has more digits ignoring leading zeroes or the number of digits is the same and the first digit which differs is larger. For real numbers written in decimal notationa slightly different variant of the lexicographical order is used: the parts on the left of the decimal point are compared as before; if they are equal, the parts at the right of the decimal point are compared with the lexicographical order.
When negative numbers are also considered, one has to reverse the order for comparing negative numbers. This is not usually a problem for humans, but it may be for computers testing the sign takes some time.
This is one of the reasons for adopting two's complement representation for representing signed integers in computers. This formatting scheme has the advantage that the lexicographical order on sequences of characters that represent dates coincides with the chronological order : an earlier date is smaller in the lexicographical order than a later date.
This date ordering makes computerized sorting of dates easier by avoiding the need for a separate sorting algorithm. The monoid of words over an alphabet A is the free monoid over A.
That is, the elements of the monoid are the finite sequences words of elements of A including the empty sequence, of length 0and the operation multiplication is the concatenation of words.
However, in general this is not a well-ordereven if the alphabet A is well-ordered. Since many applications require well orders, a variant of the lexicographical orders is often used. If the order on A is a well-order, the same is true for the shortlex order. The lexicographical order defines an order on a Cartesian product of ordered sets, which is a total order when all these sets are themselves totally ordered.
As evaluating the lexicographical order of sequences compares only elements which have the same rank in the sequences, the lexicographical order extends to Cartesian products of ordered sets.
