Write a c program to implement queue using two stacks

In contrast, new []int returns a pointer to a newly allocated, zeroed slice structure, that is, a pointer to a nil slice value. Read, Write, Close, Flush, String and so on have canonical signatures and meanings.

If the channel has a buffer, the sender blocks only until the value has been copied to the buffer; if the buffer is full, this means waiting until some receiver has retrieved a value.

We push every item and pop it onto the secondary stack. If at all possible, such code should be fixed. Here's a silly example. Sequential access on arrays and dynamic arrays is also faster than on linked lists on many machines, because they have optimal locality of reference and thus make good use of data caching.

If it's already a string, we want the actual string value held by the interface, while if it has a String method we want the result of calling the method.

If we name the results of nextInt it becomes obvious which returned int is which. Unrolled linked lists store several elements in each list node, increasing cache performance while decreasing memory overhead for references.

This is a common style; see the section on error handling for more examples. You can then compare your answer to mine. After import "bytes" the importing package can talk about bytes. An int is 4 bytes and a char one byte, so perhaps a struct S occupies 5 bytes? Don't worry about overflowing a punched card.

The built-in function make T, args serves a purpose different from new T. Another disadvantage of linked lists is the extra storage needed for references, which often makes them impractical for lists of small data items such as characters or boolean valuesbecause the storage overhead for the links may exceed by a factor of two or more the size of the data.

Open filename if err! It's good style to do so anyway, especially when the body contains a control statement such as a return or break. The receiver needs to be a pointer so the increment is visible to the caller.

Linked list

We then add all bar one item back, n—1. The top item can then be returned. There's nothing wrong with providing getters and setters yourself, and it's often appropriate to do so, but it's neither idiomatic nor necessary to put Get into the getter's name.

Interface embedding is very simple. For example, if you are only interested in memory leak errors, it is sufficient to record the allocation stack traces.Implement Queue Using Two Stacks Replicate the functionality of a queue using two stacks.

A Queue is a First-in-first-out (FIFO) data structure. If you push item A, B and C in that order, then pop three times, you will get A, B and C. To write this test, I’ve created an add method- I’ve chosen to use Strings. We could generecise it. So it is obvious that for the same input order of elements, output of the queue is exactly reverse of the output of a stack.

As we know how to reverse a stack using an extra stack, we can construct a queue using two stacks. Our queue model will consist of two stacks.

In order to implement stack using queues, This could be optimized as we use only one queue, instead of two. Algorithm. Can anyone give me the code implement in c language?

No matter on which language you have expertise it’s expected that you are familiar with fundamental of programming and can solve problems without taking help of API. c program for implement a stack using two queue First push the given elements in stack1 then pop those elements and push them in 2nd stack.

In computer science, a stack is an abstract data type that serves as a collection of elements, with two principal operations.

push, which adds an element to the collection, and; pop, which removes the most recently added element that was not yet removed.; The order in which elements come off a stack gives rise to its alternative name, LIFO (last in, first out).
