Explore the solution to the balanced brackets problem by understanding how to use loops and conditional logic to track bracket pairs. This lesson helps you grasp fundamental coding techniques for checking balance in sequences and provides a detailed, step-by-step code explanation.

We'll cover the following...

Solution

Let’s explore the solution to the problem of balanced brackets.

Python 3.10.4
def check_balance(brackets):
    check = 0
    for bracket in brackets:
        if bracket == '[':
            check += 1
        elif bracket == ']':
            check -= 1
        if check < 0:
            break
    return check == 0
bracket_string = '[[[[]]'
print(check_balance(bracket_string))

Explanation

Here’s a line-by-line explanation of the code for the Balanced Brackets problem:

  • Line 1: Defines the function check_balance that takes one argument brackets, a string of brackets.
