Consider strings that can be split so that their first half is the same as their second half (ignoring blanks, punctuation, and case). For example, the string "booboo" can be split into "boo" and "boo". Another example is "hello, hello". After ignoring blanks and the comma, the two halves of the string are the same. However, the string "rattan" has unequal halves, as does the string "abcab". Add a method public static boolean check(String s) to the class Array Queue (your function must be in the file ArrayQueue.java) that returns true when s has the property above and false otherwise. You must use methods from QueueInterface.java and ArrayQueue.java. Do not use stacks or recursion. // Much appreciate if you also run a test case for it.

QueueInterface.Java

public T dequeue();

/** Retrieves the entry at the front of this queue.

@return either the object at the front of the queue or, if thequeue is empty, null */

public T getFront();

/** Detects whether this queue is empty.

@return true if the queue is empty, or false otherwise */

public boolean isEmpty();

/** Removes all entries from this queue. */

public void clear();

}

// end QueueInterface
