Print bracket numbers in C++

In this article, we will discuss the print bracket numbers in C++ with their syntax, parameter, and examples.

What are Bracket Numbers?

In programming, numbering each pair of opening and closing brackets in an expression or sequence is referred to as printing bracket numbers. The structure of expressions in different contexts can be examined, parsed, or debugged with this.

Example:

Explanation:

• The five bracket pairs that we came across in this instance are printed in the order that they appeared.
• We should now develop a solution for this issue now that we are aware of it.
  We need to use a stack data structure to solve this problem. The number of left brackets will be counted using a single variable, while a stack will track the number of right brackets. Once we reach the right bracket, we will pop the left brackets from our count and push them into the stack.

Algorithm:

Step 1: fill the right bracket stack with nothing; initialize the left brackets by 1.

Step 2: Using variable i = 0 to n-1, iterate through the expression.

Step 3: It determines whether expression[i] == "(," or whether a left bracket is encountered. PRINT "leftBracket" is the next step (Step 3.1).

Put the leftBracket value into the stack in step 3.2.

Next step: leftBracket++.

Step 4: if the right bracket, or expression[i] == ")" Next, print the top of the stack (Step 4.1).

Pop the top element of the stack in step 4.2.

Step 5: EXIT OR ABORT

Example Code:

Let us take an example to illustrate the bracket number in C++.

Output:

Expression: (a+(b*c))+(d/e)
Bracket Numbers: 1 2 2 1 3 3

Explantion:

• In this example, the following bracket pairs appear in the expression "(a+(b*c))+(d/e)": (1) (2) (2) (1) (3) (3).
• For every opening and closing bracket, the code prints the matching bracket numbers correctly.

Example 2:

Let us take another example to illustrate the bracket number in C++.

Output:

Original Expression: ()((())()())
Bracket Numbers: 100 100 101 102 103 103 102 104 104 105 105 101

Example 3:

Let us take another example to illustrate the bracket number in C++.

Output:

Original Expression: (((a+b)*(c-d))+e)
Bracket Numbers: 1 2 3 3 4 4 2 1

Conclusion:

In C++, printing bracket numbers requires giving each pair of opening and closing brackets in an expression a distinct identity. This procedure helps with debugging and parsing tasks by making the expression's structure easier to visualize and analyze.

Bracket numbers may be produced quickly and printed next to the original expression by utilizing stacks and iterative algorithms. The hierarchical relationships between the various components of the expression can be better understood with the aid of these bracket numbers. Developers can improve their capacity to decipher and work with intricate expressions, leading to more reliable and effective software solutions, by integrating this functionality into C++ programs.
