Method changeWords executes a find and replace like you would with ctrl+f
           or command+f on here
           The first value provided is the text that you search
           Turn the text into an array of strings
           find the string that is sent in the second position (find) and
           replace it with the

          changeWords("never have I ever", "ever", "cheated") returns ["never", "have", "I", "cheated"]
           changeWords("Why why Why", "Why", "because") returns ["becasue", "because", "because"]
           changeWords("What is up bro", "hi", "hello") returns ["what", "is", "up", "bro"]
           changeWords("Hi nice to meet you", "hi", "hello") returns ["hello", "nice", "to", "meet", "you"]
           changeWords( "", "", "") returns []

          @param String text, String of multiple words
           @param String find, the string to be replaced
           @param String replace, the string to be inserted in place of find
          @return String array, where words is the array of words after the edit is made
      */
public static String[] changeWords(String text, String find, String replace)
{
       //your code here
       String[] words = new String[0];//you are free to edit this line

import java.util.Arrays;

public class StringReplace {
        public static void main(String[] args) {
                String arr[]=changeWords("never have I ever", "ever", "cheated");
                String arr2[]=changeWords("Why why Why", "Why", "because");
                for(String x:arr)
                        System.out.print(x+" ");
                System.out.println();
                for(String x:arr2)
                        System.out.print(x+" ");
                
                
        }
        public static String[] changeWords(String text, String find, String replace)
        {
                // splitting the string into words
                String words[] = text.split(" ");
                // iterating through the words
                for(int i=0;i<words.length;i++) {
                        //checking if we have find than replcae it
                        if(words[i].equalsIgnoreCase(find))
                                words[i]=replace;
                }
                return words;
