字符串处理

    给定输入asv<<bd< 输出 asb,输入xdb<yxh<z输出xdyxz

public static String process(String input) {
    char[] tempArray = new char[input.length()];
    int count = 0;
    char[] array = input.toCharArray();
    for (char c : array) {
        if (c == '<' && count > 0) {
            count--;
        } else {
            tempArray[count] = c;
            count++;
        }
    }
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i < count; i++) { 
       sb.append(tempArray[i]);
    }    
return sb.toString();
}
