Write an algorithm for printing a singly linked list in reverse

Compile time memory management[ edit ] Main articles: We start from one point.

Stack (abstract data type)

You need to solve this problem without iterating twice. Note that the cons procedure is asymmetric in how it handles list arguments, because of how lists are constructed. Post order traversal without recursion solution Remember, a prime number is a number which is not divisible by any other number e.

It has a much smaller set of standard features but with certain implementation features such as tail-call optimization and full continuations not specified in Common Lisp.

A list is nothing more than an aggregate of linked conses. This allows easy writing of programs which manipulate other programs metaprogramming. The top and bottom terminology are used irrespective of whether the stack actually grows towards lower memory addresses or towards higher memory addresses.

Any unquoted expressions are recursively evaluated before the enclosing expression is evaluated. Stack pointers may point to the origin of a stack or to a limited range of addresses either above or below the origin depending on the direction in which the stack grows ; however, the stack pointer cannot cross the origin of the stack.

Backtracking Another important application of stacks is backtracking. Very often the choice of the right data structure makes the program much more efficient — we could save memory and execution time and sometimes even the amount of code we write.

The "quote" before the foo in the preceding example is a "special operator" which returns its argument without evaluating it. The important feature is that the bottom of the stack is in a fixed position.

Most new activity is focused around implementations of Common LispSchemeEmacs LispClojureand Racketand includes development of new portable libraries and applications.

How will you find the size of a java object. Every stack has a fixed location in memory at which it begins. If the stack points to the current topmost item, the stack pointer will be updated before a new item is pushed onto the stack; if it points to the next available location in the stack, it will be updated after the new item is pushed onto the stack.

Branch and bound is a technique for performing such backtracking searches without exhaustively searching all of the potential solutions in such a space. The following will demonstrate both implementations, using pseudocode. These small programs touch several important areas e. This is generally considered one of the main advantages of the language with regard to its expressive power, and makes the language suitable for syntactic macros and metacircular evaluation.

A stack pointer, usually in the form of a hardware register, points to the most recently referenced location on the stack; when the stack has a size of zero, the stack pointer points to the origin of the stack.

Write a code that will remove the duplicates from a sorted array. Any unquoted expressions are recursively evaluated before the enclosing expression is evaluated.

What is the difference between asp and asp. For each position in the array, the stack is popped until a smaller value is found on its top, and then the value in the new position is pushed onto the stack. Most commonly used data structures are the linear list data structures.

The open source community has created new supporting infrastructure: Depending again on the exact implementation, at the end of a push operation, the stack pointer may point to the next unused location in the stack, or it may point to the topmost item in the stack.

Expressions are written as lists, using prefix notation. Lisp was only the second language after Smalltalk and is still one of the very few languages to possess such a metaobject system.

Transpose a matrix solution What are the various problems faced by using distributed database Systems.

Lisp (programming language)

Find middle element of linked list solution The program should meet the output given by the exercise itself. In contrast, most RISC CPU designs do not have dedicated stack instructions and therefore most if not all registers may be used as stack pointers as needed.

It is designed to be a pragmatic general-purpose language. Like we already mentioned, an ADT can have several implementations. EuLisp — attempt to develop a new efficient and cleaned-up Lisp. Lisp (historically, LISP) is a family of computer programming languages with a long history and a distinctive, fully parenthesized prefix notation.

Originally specified inLisp is the second-oldest high-level programming language in widespread use today. Only Fortran is older, by one year. Lisp has changed since its early days, and many. C Programs: String Operations With using Library Function.

No Programs; 1: C Program to Sort set of strings in alphabetical order using strcmp(). In computer science, a stack is an abstract data type that serves as a collection of elements, with two principal operations.

Java Programs and Examples with Output

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).

Anybody knows how to print single-linked list in reverse order (one pass and a fixed and independent of the number of elements RAM). Reverse-printing single-linked list. I think is reasonable to assume any decent implementation of a singly linked list will keep track of its size, head and tail.

Mar 15,  · Write an algorithm for printing a singly linked list in reverse, using only constant extra space. This instruction implies that you cannot use recursion but you may assume that your algorithm is a list member function.

Coding Puzzles

I heard an interview question: "Print a singly-linked list backwards, in constant space and linear time." My solution was to reverse the linkedlist in place and then print it like that.
