Consider the following recursive method, which is intended to return a String with any consecutive duplicate characters removed.

For example, removeDupChars("aabcccd") returns "abcd".public static String removeDupChars(String str){if (str == null || str.length() <= 1){return str;}else if (str.substring(0, 1).equals(str.substring(1, 2))){return removeDupChars(str.substring(1));}else{/* missing code */}}Which of the following can replace /* missing code */ so that removeDupChars works as intended?A. return removeDupChars(str.substring(2));B. return removeDupChars(str.substring(1)) + str.substring(0, 1);C. return removeDupChars(str.substring(2)) + str.substring(1, 2);D. return str.substring(0, 1) + removeDupChars(str.substring(1));E. return str.substring(1, 2) + removeDupChars(str.substring(2));

Answer:

D. return str.substring(0, 1) + removeDupChars(str.substring(1));

Explanation:

The logic here is following:

If the there are consecutive duplicate characters, return the removeDupChars method. The parameter of the removeDupChars method is a string, but the duplicate of the first character is removed from the string. The else-if part of the program does this job.

If the consecutive characters are not duplicated, return the first character of the string and the removeDupChars method. The parameter of the removeDupChars method is the rest of the string characters. The else part of the program does this job.

When the length of the str becomes one (or when the str is null), the program reaches its base and returns the str. The if part of the program does this job.

How to create a function, called separate_int_and_str, which takes in a list and separates out the integer values and strings in
gregori [183]

Answer:

program :

def separate_int_and_str(list_1):# function to seprate the list.

   str_list=[] #list to hold the

   int_list=[]#list which holds the integer value.

   for x in list_1: #for loop to extract the list.

       if(type(x)==str): #if condition to check the type of the element.

           str_list.append(x)#create a list for the string value.

       elif(type(x)==int): #check condition for th einteger value.

           int_list.append(x)#create a list for the integer value.

Explanation:

  • The above-defined function is written in the python language, which used the code to separate the list for integer and the string value.
  • There are two lists define in the function which holds the integer and the string value separately.
  • There is a 'for' loop which scans the element of the list and checks the list by the help of type function which tells the class of the element.
  • Then if the type function states that the element is from the strong class, it will assign the element on the string list otherwise it assigns the element in the integer list.
