Balanced Brackets

    It can be optimized with regex, but here is a solution that can help solving many balancing issues. the idea is to strip all the valid brackets, till we are left with no valid ones. Solution is in Typescript:

    function isBalanced(s: string): string {
    // Write your code here
    let replacedCount = Infinity;
    while (replacedCount > 0) {
        const start = s.length
        s = s.replace('()', '').replace('{}', '').replace('[]', '');
        const end = s.length;
        replacedCount = start - end;
    }
  
  return s.length === 0 ? 'YES' : 'NO';
}
