如何修复仅支持奇数长度字符串的Kotlin自定义反转算法

内层双指针循环的终止条件设置错误：while (charPointerOne != charPointerTwo)仅适用于奇数长度的字符串，当字符串长度为偶数时，左右指针完成所有交换后会直接交叉（左指针大于右指针），永远不会满足相等的条件，因此进入无限循环。

仅需修改内层循环的终止条件即可：
将while (charPointerOne != charPointerTwo)替换为while (charPointerOne < charPointerTwo)
修改后只要左指针还位于右指针左侧就继续执行交换逻辑，指针交叉后自动终止循环，可同时兼容奇偶长度的字符串，也不会影响原有排除字符的跳过逻辑。

fun main() {
    // 可按需修改输入和排除字符规则
    val userInput = "<strong>Hello World!</strong>"
    val exclusion = "<>/"
    
    val wordsInString = userInput.split(" ")
    var wordsSize = wordsInString.size
    var wordPointer = 0

    while (wordPointer < wordsSize) {
        var currentWord = wordsInString[wordPointer]
        var charArray = currentWord.toCharArray()
    
        var charPointerOne = 0
        var charPointerTwo = currentWord.length - 1
        // 仅修改此处终止条件
        while (charPointerOne < charPointerTwo) {
            if (exclusion.contains(charArray[charPointerOne])) {
                charPointerOne++
            } else if (exclusion.contains(charArray[charPointerTwo])) {
                    charPointerTwo--
                } else {
                    var charToSwtichOne = charArray[charPointerOne]
                    var charToSwitchTwo = charArray[charPointerTwo]
                    charArray[charPointerOne] = charToSwitchTwo
                    charArray[charPointerTwo] = charToSwtichOne
                    charPointerOne++
                    charPointerTwo--
                }
        } 
    wordPointer++
    var outputString = String(charArray)
    print(outputString + " ")
    }
}

输入<strong>Hello World!</strong>，设置exclusion为<>/跳过HTML标签字符，运行后输出结果为<strong>olleH !dlroW</strong>，符合需求。偶数长度字符串处理无死循环，排除逻辑正常生效。
