In python, the function slice_middle takes a string parameter, word.
- If the length of word is less than 3, the function returns the empty string.
- Otherwise, the function returns a substring made of all but the first and last characters in word.
For example:
Test | Result |
---|---|
print(slice_middle("onion")) | nio |
print(slice_middle("?")) | |
print(slice_middle("slicing")) | licin |

- In python, The function count_contains_x takes a list of strings (wordList) and returns the count of how many strings in the list contain at least one upper- or lower-case 'x'. Hint: Use the accumulator pattern to accumulate the count. Hint: You might want to use the string method count. For example: Test Result strlist = ["xerox", "OXEN", "whiffleball", "XOXOX"] print(count_contains_x(strlist)) 3 fish = ["angel", "gold", "cat", "puffer", "damsel"] print(count_contains_x(fish)) 0 strlist = ["X", "x"] print(count_contains_x(strlist)) 2 list_of_one_x = ["x"] print(count_contains_x(list_of_one_x)) 1In python, The function decodeFromAscii takes a list L of integers in the range 32 through 126. Each item in L is an ASCII code representing a single printable character. The function accumulates the string of characters represented by the list of ASCII codes and returns that string. For example, decodeFromAscii([78, 105, 99, 101, 33]) returns "Nice!" because N is chr(78), i is chr(105), c is chr(99), etc. Note: ASCII was created in the 1960's so programmers could have a standard encoding for common keyboard characters as numbers. It was later expanded to create Unicode so that characters from languages other than English, mathematical symbols, and many other symbols could also be represented by numerical codes. For example: Test Result print(decodeFromAscii([36, 49, 44, 48, 48, 48])) $1,000 print(decodeFromAscii([115, 110, 111, 119])) snowwrite the following as a function that takes in a string and returns a string. for (int i=0; i != user_string. size(); i++){ if (islower(user_string[i])){ user_string[i]=toupper(user_string[i]); } elseif(isupper(user_string[i])){ user_string[i]=tolower(user_string[i]); } } cout<<user_string; return0; }
- Use for loop in Java language Write the method stringSplosion().* * The method takes one parameter, a non-empty String str (such as "Code") and* returns a String in the form "CCoCodCode". Notice that this includes the* first character of the original String, followed by the first two characters,* and so on until the whole String is used.* * Examples: stringSplosion("Code") returns "CCoCodCode" stringSplosion("abc")* returns "aababc" stringSplosion("x") returns "x"* * @param str the input String to process.* @return a new String as described above.In computational geometry, often you need to find the rightmost lowest point in a set of points. Write the following function that returns the rightmost lowest point in a set of points:# Return a list of two values for a pointdef getRightmostLowestPoint(points):Write a test program that prompts the user to enter the coordinates of six points and displays the rightmost lowest point.Counting hashtags Write Python code to count the frequency of hashtags in a twitter feed. Your code assumes a twitter feed variable tweets exists, which is a list of strings containing tweets. Each element of this list is a single tweet, stored as a string. For example, tweets may look like: tweets = ["Happy #IlliniFriday!", "It is a pretty campus, isn't it, #illini?", "Diving into the last weekend of winter break like... #ILLINI #JoinTheFight", "Are you wearing your Orange and Blue today, #Illini Nation?"] Your code should produce a sorted list of tuples stored in hashtag_counts, where each tuple looks like (hashtag, count), hashtag is a string and count is an integer. The list should be sorted by count in descending order, and if there are hashtags with identical counts, these should be sorted alphabetically, in ascending order, by hashtag. From the above example, our unsorted hashtag_counts might look like: [('#illini', 2), ('#jointhefight', 1),…
- In python: Implement the get_num_of_non_WS_characters() function. get_num_of_non_WS_characters() has a string parameter and returns the number of characters in the string, excluding all whitespace. Implement the get_num_of_words() function. get_num_of_words() has a string parameter and returns the number of words in the stringThe Python function fourthMultLast below should take a list of numbers as input and return the sum of the third element and the last element of the list. For example, if the input list is 1,2,3,4,5,6,7,8,9, the function should return 36 which is the multiply 4 and 9. ############ ###### ##### 1def fourthMultLast (inList): ans = inList[4] 2 3 return ans #####; #### ##### There is an Error on line number 2. Fix the bug. Note: You should only make changes to line number 2. For example: Test inList[-1] ### Only change this line of code fourthMultLast([1,2,3,4,5,6,7,8,9]) 36 2 3 Answer: (penalty regime: 0, 0, 5, 10, 15, 20, 25, 30 %) Reset answer 1def fourthMultLast(inList): Precheck Result Check ans = inList[4] * inList[-1] ### Only change this line of code return ans PIN JAVA SCRIPT Programming Create a function that takes a string as an argument and returns true if each letter in the string is surrounded by a plus sign.
