WebDec 10, 2024 · For implementing queue, we need to keep track of two indices, front and rear. We enqueue an item at the rear and dequeue an item from the front. If we simply increment front and rear indices, then there may be problems, the front may reach the end of the array. The solution to this problem is to increase front and rear in circular manner. WebNov 28, 2024 · An implementation of a queue Q, using two stacks S1 and S2, is given below: void insert (Q, x) { push (S1, x); } void delete (Q) { if (stack-empty (S2)) then if (stack-empty (S1)) then { print (“Q is empty”); return; } else while (! (stack-empty (S1))) { x=pop (S1); push (S2,x); } x=pop (S2); }
