So the first character of the string is on the bottom of the stack and the last element of a string is on the top of the stack. Here one by one each character gets inserted into the stack.

String reversal is also another application of stack.

Each program that is running in a computer system has its own memory allocations

In Memory management, any modern computer uses a stack as the primary management for a running purpose.

In Graph Algorithms like Topological Sorting and Strongly Connected Components.

To get back from a current state we need to store the previous state for that purpose we need a stack. Some examples of backtracking are the Knight-Tour problem, N-Queen problem, find your way through a maze, and game-like chess or checkers in all these problems we dive into someway if that way is not efficient we come back to the previous state and go into some another path.

Backtracking is one of the algorithm designing techniques.

Used in many algorithms like Tower of Hanoi, tree traversals, stock span problems, and histogram problems.

The height of the memory stack is flexible as it occupies a large amount of memory data. Memory Stack: This type of stack can handle a large amount of memory data.The height of the register stack is always limited as the size of the register stack is very small compared to the memory. Register Stack: This type of stack is also a memory element present in the memory unit and can handle a small amount of data only.So, it can be simply seen to follow the LIFO/FILO order. the plate which has been placed at the bottommost position remains in the stack for the longest period of time. The plate which is at the top is the first one to be removed, i.e. Consider the simple example of plates stacked over one another in a canteen. There are many real-life examples of a stack. Returns true if the stack is empty, else false.Įnd procedure Understanding stack practically: If the stack is empty, then it is said to be an Underflow condition. The items are popped in the reversed order in which they are pushed. If the stack is full, then it is said to be an Overflow condition.
