- 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 stringInclude this code: public static boolean isMatched(String expression) {final String opening = "({["; // opening delimitersfinal String closing = ")}]"; // respective closing delimitersStack<Character> buffer = new LinkedStack<>( ); // Using Textbook ADT, not Java libraryfor (char c : expression.toCharArray( )) {if (opening.indexOf(c) != −1) // this is a left delimiterbuffer.push(c);else if (closing.indexOf(c) != −1) { // this is a right delimiterif (buffer.isEmpty( )) // nothing to match withreturn false;if (closing.indexOf(c) != opening.indexOf(buffer.pop( )))return false; // mismatched delimiter}}return buffer.isEmpty( ); }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",…
- Given string userInput on one line and string endString on a second line, assign concatStr with the copy of userInput with endString appended. Ex: If the input is: Fuzzy bear !!! then the output is: Fuzzy bear!!! #include <iostream> #include <string> using namespace std; int main() { string userInput; string endString; string concatStr; getline(cin, userInput); getline(cin, endString); /* Your code goes here */ cout << concatStr << endl; return 0; }Create a function that removes the first and last characters from a string. In c# Examples RemoveFirstLast("hello") - "ell" RemoveFirstLast ("maybe") - "ayb" RemoveFirstLast("benefit") - "enefi" RemoveFirstLast("a") - "a" Note If the string is 2 or fewer characters long, return the string itself (See example # 4).What happens if you try to use an invalid index to access a character in a string?
- Given string givenInput on one line and string endString on a second line, assign resultStr with the copy of givenInput appended with a "*", then with endString.
