2. Write a function that, given a list of lists, returns the total length of all the lists. This problem can be solved two different ways.

(defun totalLength(mylist)
(setq total 0)
(loop
    (setq total (+ total (length (car mylist))))
    (setf mylist (cdr mylist))
    (if (endp mylist) (return))
   )
   total
)

(format t "~%Total length of list: ~s ~%~%" (totalLength '((a) (a b) (a b c))))

output

3. Write a program that prompts the user to enter two numbers and then outputs the sum of the two numbers.

(write-line "Enter first number")
(setq number1 (read))
(write-line "Enter second number")
(setq number2 (read))
(setq total (+ number1 number2))
(format t "~%~s+~s=~s ~%" number1 number2 total)

output

Write a function in lisp XIT that counts the number of items in each sub-list of a list and returns the count in a list. It should only work if there are two levels of brackets in the parameter (simple lists inside the parent list). Thus:             (XIT '((A B C)))        -> (3)             (XIT '((A) (A B) (A B C))) -> (1 2 3)             (XIT '((1 2)))              -> (2)             (XIT '(1 (2 3)))...

LISP Programming Language Write a Bubble Sort program in the LISP Programming Language called “sort” that sorts the array below in ascending order.  LISP is a recursive language so the program will use recursion to sort. Since there will be no loops, you will not need the variables i, j, and temp, but still use the variable name array for the array to be sorted.             Array to be sorted is 34, 56, 4, 10, 77, 51, 93, 30, 5, 52 The...

We were asked this: Write a function that takes a list, and returns a list representing each word whose reverse is also in the list. def find_reversals(lst: List[str]) -> List[str]: Each pair, such as 'abut', 'tuba', should be represented by the first element encountered. Don't report the same pairs twice. Don't list palindromes.

Write a C++ program that has a function which given n>=0, create an array length n*n with the following pattern, shown here for n=3 : {0, 0, 1, 0, 2, 1, 3, 2, 1} (spaces added to show the 3 groups) generateGroups(3) → [0, 0, 1, 0, 2, 1, 3, 2, 1] generateGroups(2) → [0, 1, 2, 1] generateGroups(4) → [0, 0, 0, 1, 0, 0, 2, 1, 0, 3, 2, 1, 4, 3, 2, 1]

Write a Python function that returns a list of keys in aDict with the value target. The list of keys you return should be sorted in increasing order. The keys and values in aDict are both integers. (If aDict does not contain the value target, you should return an empty list.) This function takes in a dictionary and an integer and returns a list. def keysWithValue(aDict, target): ''' aDict: a dictionary target: an integer ''' # Your code here

Python program. Write a function called cleanLowerWord that receives a string as a parameter and returns a new string that is a copy of the parameter where all the lowercase letters are kept as such, uppercase letters are converted to lowercase, and everything else is deleted. For example, the function call cleanLowerWord("Hello, User 15!") should return the string "hellouser". For this, you can start by copying the following functions discussed in class into your file: # Checks if ch is...
