This is almost a duplicate of: How to restructure multi-dimensional array with columns as rows? and Combining array inside multidimensional array with same key This can be done with foreach loops, but I like the condensed variadic method (PHP 5.6+). You can research the aforementioned links to see the other techniques if your version isn’t … Read more
I ran your code just as it is, and it printed it both in uppercase and lowercase, but I noticed you had a comment that said //Display the first character, and following it, keyboard.next(). This was the only incorrect part. To print the first letter of a string(in this case the string is city), use … Read more
Im not going to implement the solution for you but I’ll give you the pusedocode. for each letter1 in String1 for each letter2 in String2 if letter1 is letter2 then print its position So you know you will need a nested for loop and a comparison, it becomes a bit more complicated if you want … Read more
You can use the Regex pattern <.*?> to retrieve each word, ie MatchCollection matches = Regex.Matches(input, “<.*?>”); You can then iterate over the collection to get the tags. 2 solved Get String with Specific Tags in C#
All of your logic is in the while loop right now, so it will keep repeating over and over. It will keep saying you are an Orc and restarting the adventure over again. If you want to develop this in maybe a better way, I would suggest looking up the concept of “ticks” and state … Read more
The total variable will contain the number of unique characters in the array str. This happens because you increment the count(total+=!used[str[i]-‘a’]) only if you haven’t already marked the character as visited. If you incremented it, you mark it as such in the next line (used[str[i]-‘a’]=1) so that you wont count it again. The notation str[i]-‘a’ … Read more
A simple way: String str = “Good Morning”; String subStr=str.substring(0,7); char[] arr = subStr.toCharArray(); Arrays.sort(arr); for(int i = arr.length – 1; i >= 0; i–) System.out.print(arr[i]); solved How can I take a part of a string and sort it in reverse alphabetical order? [duplicate]
To acomplish your goal you need to do two steps: Read the entire file. Transform to appropiate structure. Thanks to LINQ you can accomplish quickly: var cells = (from l in System.IO.File.ReadAllLines(“myfile.txt”) select l.Split(” “.ToArray(), StringSplitOptions.RemoveEmptyEntries)).ToArray(); Now you can access the cells like this: var value = cells[1][2]; 3 solved C# Readint a txt file … Read more
Files#lines returns a stream of all the lines in the file. You could join these lines to a single string, and then split it according to the separator: String separator = “:”; // for example… String entireFile = Files.lines(Paths.get(“file.txt”)).collect(Collectors.joining()); String[] separated = entireFile.split(separator); solved How to read txt file and save as a single string … Read more
Change the 9 to a 10: if temp2[4] == ‘-‘ and temp2[10] != ‘-‘: temp3 = temp2[:10] + ‘-‘ + temp2[10:] When you call a string its str[from:to], so temp2[:9] is equivalent to temp2[0:9] and it would only return the characters from 0-9 instead of the required 0-10 0 solved Python String unwanted overwrite
I hope this is what you need: snake_case = “” variableName = “parselTongue” for character in variableName: if character.isupper(): snake_case += “_”+character.lower() else: snake_case += character print(snake_case) 2 solved What will be the code for this? you have to solve with python
Not a library but an easy way to do what you want: string_a=”ABCD” string_b = ‘ADCT’ print ([ind for ind,char in enumerate(string_a) if string_b[ind] != char]) [1, 3] enumerate gives you the index of each char through the string, if string_b[ind] != char checks if the chars at corresponding indexes are not the same. string_b … Read more
For approach 1, all you need to do is remove the call to sc.nextLine() and everything will be fine. That’s because each line contains a “token” i.e. a word, delimited by whitespace. That’s what sc.next() will return. No need to call nextLine() after that. For your approach 2, you should carefully read the API documentation … Read more
String refers to an individual string, whereas [String] is an array of strings. I think your error may be that you have done: var name : String = nameList [2] Where you should have done: var name : String = nameList[2] I assume that in the first instance it thinks you are setting name as … Read more
An alternative to the StringBuilder approach: static class StringExt { public static string InsertAfterEvery( this string source, string insert, int every, string find) { int numberFound = 0; int index = 0; while (index < source.Length && index > -1) { index = source.IndexOf(find, index) + find.Length; numberFound++; if (numberFound % every == 0) { … Read more
