哈夫曼树循环寻找最小下标无法找到T？？

Question

哈夫曼树循环寻找最小下标无法找到'T'。

The Chinese official said he viewed the Trump Presidency not as an aberration but as the product of a failing political system.This jibes with other accounts.The Chinese leadership believes that the United States, and Western democracies in general, haven't risen to the challenge of a globalized economy, which necessitates big changes in production patterns, as well as major upgrades in education and public infrastructure. In Trump and Trumpism, the Chinese see an inevitable backlash to this failure.

以下是主要代码，编码之后发现只有‘T’编不出来。

//判断字符是否重复出现过
bool JudgeWords(char ch, int j)
{ 
    int i = 0;
    for (i = 0; i < j; i++)//重复出现
    {
        if(HT[i].data==ch)
            return true;//1
    }
    return false;//0
}
//计算各个字符个数以及频率
int CountWords(char* s)
{
    int j = 0,Total=0;
    for (int i = 0;s[i]!='\0'; i++)
    {
        char ch = s[i];
        if (!JudgeWords(ch, j))//没有重复
        {
            HT[j].data = ch;
            HT[j].rate = 1;//出现频率
            j++;
        }
        else//有重复
        {
            for (int k = 0; k < j; k++)
            {
                if (HT[k].data == ch)
                    HT[k].rate++;
            }
        }
    }
    for (int q = 0; q < j; q++)//计算总字符个数
    {
        Total = HT[q].rate + Total;
    }
    cout << "该篇文章不同的字符的个数为：" << j << endl;
