6 THE NTWICE PROBLEM Complete the method nTwice. The method has two inputs: a String str and an int n. The output of the method is a new String made of the first and last n chars from str. The original String length will be at least length n. Here is some sample input and output: nTwice("Hello", 2) → "Helo" nTwice("Chocolate", 3) → "Choate"

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",…
Method: sumOdds(value: int): This method will sum all the odd values from 1 upto the value passed by parameter. This will display the sumas an integer value.Method: characterCount(phrase: str): This method will count the number of characters in the phrase that is passed by parameter. You cannot useany built in function ( ie len() ) and must use a looping activity. This should display the number of characters inthe phrase as an integerMethod: multiplicationPractice(): This method is to practice simple multiplication problems. The program should randomly generate twonumbers from 1-10 for the user to multiply. It should display the multiplication problem and allow the user toanswer the problem. It should display if the user got the answer correct or incorrect. The activity shouldcontinue until the user has gotten 3 different practice problems correct.Method: order(value1: int, value2: int, value3: int): This method is to order the 3 passed value from least to greatest. It should display…

Programming in C#: Write a console-based application that displays every perfect number from 1 through 10000. A number is perfect if it equals the sum of all the smaller positive integers that divide evenly into it. For example, 6 is perfect because 1, 2, and 3 divide evenly into it and their sum is 6. Use format strings(field size 8, right alignment) to show all perfect numbers. Display the results as seen below. 6 28 496 8128
