+Write a method
+
+String endToStart(String word)
+
+which takes a string as its parameter. 
+The method constructs an inverted version of the string, where the characters of the original string are from end to beginning.
+
+
+
+
+An example of calling the method:
+public static void main(String[] args) {
+    System.out.println(endToStart("hi"));
+    
+    String word = "Hellooo";
+    String word2 = endToStart(word);
+    System.out.println(word2);
+}
+
+Program outputs:
+ih
+ooolleH
+
+
+
+
+
+
+
+
+import java.util.Random;
+
+public class Test{
+    public static void main(String[] args){
+        final Random r = new Random();
+        
+        String[] words = "first second third fourth programming class method java variable".split(" ");
+        for (String w: words) {
+            System.out.println("Testing with parameter " + w);
+            System.out.println(endToStart(w));
+            System.out.println("");
+        }
+    }
+    
+    public static String endToStart(String word) {
+        String result = "";
+        int wordLastIdx = word.length() - 1;
+        // for each word in the list
+        // go from wordLastIdx to 1st idx (0)
+        for (int i = wordLastIdx; i >= 0; i--) {
+            result += word.charAt(i);
+        }
+        return result;
+    }
+}
