func groupAnagrams(_ strs: [String]) -> [[String]] {
    var anagramMap = [String: [String]]()

    for str in strs {
        let sortedStr = String(str.sorted()) // Sort characters in the string
        anagramMap[sortedStr, default: []].append(str)
    }

    return Array(anagramMap.values)
}

let inputWords = ["eat", "tea", "tan", "ate", "nat", "bat", "tae"]
