alphabet

问题 Is there any way to get nth letter of English alphabet? I want smt similar to this: string letter = EnglishAlphabet.GetLetter(5); //result -> letter is 'E' I want to use this according to count of my list. If there is 3 elements on my list so "D:D" is enough for me but there is 4 elements then "E:E". I want use this string here: Excel.Range chartRange; Excel.ChartObjects xlCharts = (Excel.ChartObjects)xlWorkSheet.ChartObjects(Type.Missing); Excel.ChartObject myChart = xlCharts.Add(5, 5, 540,

问题 I would like to create some arrys. First of all I would like to tell you what it is about so that you understand why I am doing this: Cryptography. I want create an array with the alphabet. such as $a1 = array("a"=>"b", "b"=>"c",....,"z"=>a"); Alright, that is just a bit of typing so now I want to do it a bit more often. In this case it is x+1=y or in other words for the decoding x=y-1 So lets say I would like to do that with a position change from 1 to 26 - I would have 26 arrays than. The

问题 I would like to be able to create a sequence of letters in R (to assist in importing data from a SPSS file) It's quite easy to create a sequence of numbers, for example: seq(1,1000) [1] 1 2 3 4 5 6 ... 1000 paste("something_",1:12,sep="") [1] something1 something2 ... something12 But is there any functionality for appending, pasting, or creating sequences of letters like this? paste("This_",a:z,sep="") [1]This_a This_b This_c ... This_4z Thanks in advance! 回答1: This is what you're looking for

问题 I'm 90% sure there is a built in function that does this. I need to find the position of a character in an alphabet. So the character "b" is position 1 (counting from 0), etc. Does anyone know what the function is called? Thanks in advance! EDIT: What i'm trying to do is to send all the characters X amount of "steps" back in the alpha bet, so if i have a string with "hi" it would be "gh" if i sent it back one step. There might be a better way of doing it, any tips? 回答1: It is called index .

问题 I have an array of N elements (representing the N letters of a given alphabet), and each cell of the array holds an integer value, that integer value meaning the number of occurrences in a given text of that letter. Now I want to randomly choose a letter from all of the letters in the alphabet, based on his number of appearances with the given constraints: If the letter has a positive (nonzero) value, then it can be always chosen by the algorithm (with a bigger or smaller probability, of

问题 Given any character from a to z, what is the most efficient way to get the next letter in the alphabet using PHP? 回答1: The most efficient way of doing this in my opinion is to just increment the string variable. $str = 'a'; echo ++$str; // prints 'b' $str = 'z'; echo ++$str; // prints 'aa' As seen incrementing 'z' give 'aa' if you don't want this but instead want to reset to get an 'a' you can simply check the length of the resulting string and if its >1 reset it. $ch = 'a'; $next_ch = ++$ch;

问题 I have a question about iterate through the Alphabet. I would like to have a loop that begins with "a" and ends with "z". After that, the loop begins "aa" and count to "az". after that begins with "ba" up to "bz" and so on... Anybody know some solution? Thanks EDIT: I forgot that I give a char "a" to the function then the function must return b. if u give "bnc" then the function must return "bnd" 回答1: Edit: Made it do exactly as the OP's latest edit wants This is the simplest solution, and

问题 i'm using CMU sphinx to recognize alphabet letters, but i'm noticing very low accuracy.( <=20%). for example : when I spelling letters: A-P-P-L-E, it come out A B B L E. the accuracy is too low to be useful. I hope don't have to implement it like some posts mentioned, using "alpha""beta" etc. for improving the recognition rates. the dict file and lm file in generate in online lmtools BTW: the accuracy rate is above 80% when i limit the dict and speak to microphone with words . so does anyone

问题 This is what I have to do: Write a script in Python that is an implementation of a version of the Vigenere cipher for English text. Your script should distinguish lowercase and uppercase letters (i.e., the encryption key and the plaintext are allowed to be composed of lowercase and uppercase letters but the ciphertext should be uppercase). In addition to letters, there will be four other characters in the plain text: comma (26), dot (27), dash (28), underscore (29) changing the encryption

问题 I'm trying to create a Python function that receives a letter (a string with only one alphabetic character) and returns the 0-based numerical position of that letter in the alphabet. It should not be case-sensitive, and I can't use import. So entering "a" should return 0 Entering "A" should also return 0 Entering "O" should return 14 And so on. I had noticed this question but the top answer uses import and the second answer doesn't make any sense to me / doesn't work. I tried to apply the
