Valid Parentheses Problem Statement

Given a string 'STR' consisting solely of the characters “{”, “}”, “(”, “)”, “[” and “]”, determine if the parentheses are balanced.

Input:

The first line contains an integer 'T' representing the number of test cases. Each of the following T lines contains a string that you need to check for balanced parentheses.

Output:

For each test case, print a single line stating whether the string is balanced or not, with each result on a new line.

Example:

Input:
T = 2
STR = "{}[]()"
STR = "{[}]"
Output:
"Balanced"
"Not Balanced"

Constraints:

  • 1 <= T <= 10
  • 1 <= N <= 105

Note:

No need to print anything explicitly. Just implement the functionality to determine if the strings are balanced.
