Python Function Name: unscramble Parameters: a string Returns: a string Description: Write a function, unscramble, that takes an input string, and returns a the unscrambled version of the argument. To unscramble the string: When the string has an odd number of characters, middle character is the first character in the unscrambled result Pairs of remaining characters are added to the result, proceeding left to right from inner-most to outer-most characters. Example Call: unscramble('3cis1') Expected result: ics31 Example Call: unscramble('ocicssol') Expected...

In C++ 1.Define a function named "sumCodes" that accepts two input parameters: "s "and "pos". "s" is an object of the type "string" and "pos" is a boolean value with the default argument of "true". If "pos" is "true", the function returns the summation of the ASCII codes of all the characters located at the even indices of "s" and if "pos" is "false", the function returns the summation of the ASCII codes of all the characters located at the...

Function name : contains_substring Parameters : string (string), substring (string) Returns: bool Description : If the substring is entirely contained within the string, then return True, otherwise return False. An empty substring will always return False. The substring may be longer than the string. You are not allowed to just write “if substring in string”.

Define a function named how_many_substr_of_string(...) which receives two parameters, the first parameters is a list with strings (name it listst) and the second parameter is a single string (name it st). The function should return a number, indicating how many of the strings in the list listst are substrings in the string st As an example, the following code fragment: listst = ["a","bc","dd"] st = "abc" res = how_many_substr_of_string(listst,st) print (res) should produce the output: 2 language:Python

Language: Python Function name : findwaldo Parameters : string Returns: int Description: Write a recursive function that takes in a string containing some combination of letters, numbers, and spaces, and return the starting index of the first instance of “waldo” contained in that string. If the string does not contain “waldo”, return -1. This function IS case sensitive, so “waldo” is not the same as “WALDO”. Code using string functions such as .index() and .find() that oversimplify the problem will...

5) Define a function called remainder _is_even which receives two positive integer numbers as parameters: num and div. This function should return a boolean value. The value to be returned should be True if the remainder of dividing num by div is even and it should return False otherwise. As an example, the following code fragment: print (remainder_is_even(23,2)) should produce the output: False 6) Define a function first_last_repeated which receives as input parameter a string (orig) with at least one...

Write a function named lengthDict with the following specifications: Input (parameters): t, a string Return: a dictionary in which each key is the length of a word in t and the corresponding value is the number of words in t with that length. For example, the following would be correct output. text = "it is what it is" print(lengthDict(text)) {2: 4, 4: 1}
