Initially the queue Q is empty. The queue has the length

Initially the queue Q is empty. The queue has the length 4. At some point task A executes the following lines code: inti=18xQueueSend(Q,&i,1)i=0xQueueSend(Q,&i,1);i=21;xQueueSend(Q,&i,1); After this code is executed, the task A is paused and the task B is run instead. Suppose that task B executes the lines int j; xQueueReceive(Q, \&j, 1); What will be the value of j
