You are developing a scientific calculator app. Implement a feature to check if brackets in user input are valid. Bracket types: - Parentheses (): Basic operation grouping - Square brackets []: Array/index operations - Curly braces {}: Set operations Valid formula: All brackets open and close in correct order
"(3+[2*{1+1}])"true
All brackets properly nested: () wraps [], [] wraps {}
"(3+[2*{1+1)]"false
) comes after { - trying to close parenthesis before curly brace
