A Stack can be used for evaluating expressions consisting of operands and operators.

- It can be used for
**Backtracking**, i.e. to check parenthesis matching in an expression. - It can also be used to convert one form of expression to another form.

**There are various application of stack and some of them are given below:**

**‣ Evaluation of Arithmetic Expressions**:

Arithmetic expressions can be evaluated using various algorithms such as the shunting yard algorithm or by converting the expression into postfix notation and then evaluating it. These algorithms help in efficiently solving mathematical expressions in computer programs.

**‣ Backtracking**:

Backtracking is a fundamental technique used in Data Structures and Algorithms (DSA) to solve problems by incrementally building a solution and backtracking when you reach a dead end. It involves exploring all possible solutions and discarding those that do not satisfy the problem constraints.

**‣ Delimiter Checking**:

Delimiter checking in Data Structures and Algorithms (DSA) is a process used to ensure that delimiters such as parentheses, brackets, and braces in an expression are properly balanced and nested. This is important in programming to avoid syntax errors and ensure the correct interpretation of the code by the compiler or interpreter.

** ‣ Reverse a Data**:

Reversing data in Data Structures and Algorithms (DSA) typically refers to reversing the order of elements in a data structure such as an array, linked list, or string. The process of reversing data involves rearranging the elements in the opposite order from their original sequence.

**‣ Processing Function Calls**:

Processing function calls in Data Structures and Algorithms (DSA) involves understanding how functions are invoked, executed, and managed within a program. When a function is called in a program, the control flow transfers to the function definition, executes the statements within the function, and then returns control back to the calling code.
