- public static String pancakeScramble(String text) This nifty little problem is taken from the excellent Wolfram Challenges problem site where you can also see examples of what the result should be for various arguments. Given a text string, construct a new string by reversing its first two characters, then reversing the first three characters of that, and so on, until the last round where you reverse your entire current string.This problem is an exercise in Java string manipulation. For some mysterious reason, the Java String type does not come with a reverse method. The canonical way to reverse a Java string str is to first convert it to mutable StringBuilder, reverse its contents, and convert the result back to an immutable string, that is,str = new StringBuilder(str).reverse().toString(); Here's the tester it must pass: @Test public void testPancakeScramble() throws IOException {// Explicit test casesassertEquals("", P2J3.pancakeScramble(""));assertEquals("alu",…public static String pancakeScramble(String text) This nifty little problem is taken from the excellent Wolfram Challenges problem site where you can also see examples of what the result should be for various arguments.

The canonical way to reverse a Java string str is to first convert it to mutable StringBuilder, reverse its contents, and convert the result back to an immutable string, that is, str = new StringBuilder(str).reverse().tostring(); A bit convoluted, but does what is needed without fuss or muss. Maybe one day the Java strings will come with the reverse method built in, just like the string data types of all sensible…Provide examples of how to find the first or last time a particular character appears: string(), stringchr ()
- TAKE A LIST OF STRING FROM THE USER AND COUNT THE NUMBER OF UNIQUE ELEMENTS WITHOUT USING THE FOR, WHILE, Do-WHILE LOOPS. PREFERRED PROGRAMMING LANGUAGE: JAVA/C++Find all of the String methods, that may be used to get a portion of a string from another string Such as: "California" => "nia" Select one or more from choices provided: substr() slice() piece() charAt()Use for loop in Java language Write the method stringSplosion().* * The method takes one parameter, a non-empty String str (such as "Code") and* returns a String in the form "CCoCodCode". Notice that this includes the* first character of the original String, followed by the first two characters,* and so on until the whole String is used.* * Examples: stringSplosion("Code") returns "CCoCodCode" stringSplosion("abc")* returns "aababc" stringSplosion("x") returns "x"* * @param str the input String to process.* @return a new String as described above.
- Implement the following function which accepts a string as parameter and reverses it, without using any function from the string library. void strReverse(char *str)def emotify(string): a=string.split() l=len(a) for i in range(0,l): if(a[i]=="smile"): a[i]=":)" if(a[i]=="grin"): a[i]=":D" if(a[i]=="sad"): a[i]=":((" if(a[i]=="mad"): a[i]=">:(" print (*a) string1=input("Enter the string:\n") emotify(string1); please explain this code. this is pythonFix the code to make it work properly pls // Converts a string to lowercase, and // displays the string's length // as well as a count of letters public class DebugSeven4 { public static void main(String[] args) { String aString = "HELP!! I need to get 37 things DONE today!!"; int numLetters = 0. int stringLength = aString.Length(); System.out.println("In all lowercase, the sentence is: "); for(int i = 0; i < stringLength; i++) { char ch = Character.toTheLowerCase(aString.charAt(i)); System.out.print(ch); if(Character.isLetter(ch)) numLetters--; } System.out.println(); System.out.println ("The number of CHARACTERS in the string is " + stringLength); System.out.println(The number of LETTERS is " + numLetters); } }
- Given a long string use recursion to traverse the string and replace every vowel (A,E,I,O,U) with an @ sign. You cannot change the method header. public String encodeVowels(String s){ // Your code here }True/False 7. The split method breaks a string into a list of substrings, and j oin does the opposite.def q5(sentence): Assumes sentence is a string. Returns a list of all the words in sentence, where a word is a token separated by white space, (you can use sentence.split()), and then for each word, make it lowercase and remove any character that is not alpha-numeric (a-z or 8-9). For example, I q5("The Plague" (French: "La Peste"), 1947, by Albert CamUs.') should return ['the', 'plague', 'french', 'la', 'peste', '1947', 'by', 'albert', 'camus'] q5('Red@Dragon....ca is great!') should return ['reddragonca', 'is', 'great'] pass
