Create a class myQueueADT that implements the queue functions using a circular array implementation. Make sure the implementation keeps track of all necessary variables like the front and rear indices and the size of the queue. The functions to implement are: $1.$ qSize $$ size$()$ Returns the size of the queue. $2.$ emptyFlag $$ isEmpty$()$ Returns true if the queue is empty and false if not. $3.$ fullFlag $$ isFull$()$ Returns true if the queue is full and false if not. $4.$ firstInQ $$ peek$()$ Returns the value of the first element in the queue. Returns $-1$ if the queue is empty. $5.$ enqueue$($elementValue$)$ Adds a new element elementValue to the end of the queue. $6.$ firstInQ $$ dequeue$()$ Removes the first element in the queue and returns its value. Returns $-1$ if the queue is empty.
