Balanced Brackets

    My answer with Typescript.

    Idea is remove couple of bracket when it can, then check remaining [s], if it empty mean it fully valid brackets

    function isBalanced(s: string): string {
    let s_memo = ''

    while (s_memo != s && s.length > 0) {
        s_memo = s
        s = s.replace(/(\[\]|\{\}|\(\))/g, '')
    }

    return s.length > 0 ? 'NO' : 'YES'
}
