Given a string and a non-negative int n, we'll say that the front of the string is the first 3 chars, or whatever is there if the string is less than length 3. Return n copies of the front;

frontTimes("Chocolate", 2) → "ChoCho"
frontTimes("Chocolate", 3) → "ChoChoCho"
frontTimes("Abc", 3) → "AbcAbcAbc"

Must work the following problem using a while loop or do while.

Expert Solution

StringTimesTest.java

public class StringTimesTest {

   public static void main(String[] args) {

System.out.println(frontTimes("Chocolate", 2) );
System.out.println(frontTimes("Chocolate", 3) );
System.out.println(frontTimes("Abc", 3) );
   }
   public static String stringTimes(String s, int n){
       String returnString = "";
       int i=0;
       while(i<n){
           returnString = returnString + s;
           i++;
       }
       return returnString;
   }
   public static String frontTimes(String s, int n){
       if(s.length()<=3){
           return stringTimes(s, n);
       }
       else{
           return stringTimes(s.substring(0,3), n);
       }
   }

}

Output:

ChoCho
ChoChoCho
AbcAbcAbc

Write a recursive method repeatNTimes(String s, int n) that accepts a String and an integer as two parameters and returns a string that is concatenated together n times. (For example, repeatNTimes ("hello", 3) returns "hellohellohello") Write a driver program that calls this method from the Main program. Need code in c#.

In Java In mathematics, factorial of a non-negative integer n, denoted by n! , is the product of all positive integers less than or equal to n. For example, 5! = 5 * 4 * 3 * 2* 1 = 120 3! = 3 * 2 * 1 = 6 2! = 2 * 1 = 2 The value of 0! is 1. Write a program that asks user to enter an integer > 0; if a valid value is...

In C++ Let n be a non-negative integer. The factorial of n, written n!, is defined by 0 ! 5 1, n! = 1·2·3· · ·n if n $ 1. For example, 4! = 1·2·3·4 = 24. Write a program that prompts the user to enter a nonnegative integer and outputs the factorial of the number. Allow the user to repeat the program. Example: If the user enters a 3 then your program should perform answer = 3 * 2...

This is JAVA Return the centered average of an array of ints, which we'll say is the mean average of the values, except ignoring the largest and smallest values in the array. If there are multiple copies of the smallest value, ignore just one copy, and likewise for the largest value. Use int division to produce the final average. You may assume that the array has a length of 3 or more. 1 public int centeredAverage(int[] nums) 2 { 3...

public int static mirroringIt(String str){ return n; } implement this function so its takes ONE string and remove the characters so it becomes a mirrored word. example: Input: qswwbi Output: 4 remove q s b i "wow" is a mirror word. output : 0 Input : "if" output : 1 remove either I or f because it's two words. don't use 3rd parties library or java.util.

The factorial of a non-negative integer is defined as follows: n! = 1 × 2 × ... × (n − 1) × n A. Write a function that takes an input value n and returns its factorial result n!. Ensure that your function returns an error statement if the input n is either a negative or a non-integer value. You cannot use the prod() or factorial() functions. The Euler number e is calculated as the sum of the infinite series...
