# Bracket checking [duplicate]

Consider a string like:

a.push(c.push("a",["ad","bd",2,{"ard",duo}]).pop().replace(2,"tg").enc([3,{2,adf},"atr"],5)


Write a program that will verify whether a string is correctly bracketed. A correctly bracketed string can be defined as one in which all brackets are terminated (closed), and the inner brackets are terminated before outer ones. Below are example strings:

Correctly bracketed:

• a.push(a,{b,[c,d]})

Incorrectly bracketed:

• a.push(a,{b)}

Your program must be able to deal with the following types of brackets:

• Curly (flower) brackets {}
• Square brackets []
• Parantheses ()

If necessary, the string may contain any of these characters:

• Alphabets, uppercase and lowercase (A-Z, a-z)
• Numerics (0-9)
• Double quotes ("), but not single quotes
• Arithmetic operators (+, -, *, /)
• Dots (.)
