Algorithm for queue using linked list






Algorithm:



Step1: Start

Step2: Read the case in ch

Step3: Switch ch

        Case1, perform enq function
          
        Case2, perform deq function
           
        Case3,perform display function

        Case4, exit

Step4: enq function

       1.read element in item
       2.data[temp]=item
       3.link[temp]=null
       4.if rear=null,then set front=temp and rear=temp
       5.else
          link[rear]=temp
          rear=temp
      
       deq function
   
       1.if front=null,then print queue is empty
       2.else
           Set item=data[front]
       3.if front=rear,then set front=rear=null
       4.else,
          front=link[front]

       display function
           Print the elements in the queue

Step5: stop
