G what does the following piece of code do a) Print the duplicate elements in the array b) Print the element with maximum frequency c) Print the unique elements in the array d) None of the mentioned

a) Print the duplicate elements in the array

Explanation:

I found this code:

This is two for cycle, where we make a comparison among two variables i and j to print duplicate elements.

for (int i=0; i < arr.length-1; i++)

{

for (int j = i+1; j < arr.length; j++)

 {

   if (( arr[i].equals(arr[j])) && (i != j))

       {

         System.out.println(arr[i])

}

}

}

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
