What is stack in Scala?
A stack is a data structure that follows the last-in, first-out(LIFO) principle. We can add or remove element only from one end called top. Scala has both mutable and immutable versions of a stack. Syntax : Stack var s = Stack[type]() // OR var s = Stack(val1, val2, val3.)
What is stack implementation of stack?
A stack can be implemented by means of Array, Structure, Pointer, and Linked List. Stack can either be a fixed size one or it may have a sense of dynamic resizing. Here, we are going to implement stack using arrays, which makes it a fixed size stack implementation.
What is ListBuffer in Scala?
A list is a collection which contains immutable data. List represents linked list in Scala. A List is immutable, if we need to create a list that is constantly changing, the preferred approach is to use a ListBuffer.
How do you write a loop in Scala?
In Scala, for-loop allows you to filter some elements from the given collection using one or more if statements in for-loop. Syntax: for(i<- List if condition1; if condition2; if condition3; …) { // code.. }
What is Scala List?
A list is a collection which contains immutable data. List represents linked list in Scala. The Scala List class holds a sequenced, linear list of items. Lists are immutable whereas arrays are mutable in Scala. Lists represents a linked list whereas arrays are flat.
Is empty stack in C?
IsEmpty: Checks whether the stack is empty. IsFull: Checks whether the stack is full. Top: Displays the topmost element of the stack.
What is the difference between SEQ and list in Scala?
A Seq is an Iterable that has a defined order of elements. Sequences provide a method apply() for indexing, ranging from 0 up to the length of the sequence. Seq has many subclasses including Queue, Range, List, Stack, and LinkedList. A List is a Seq that is implemented as an immutable linked list.
