# Fill in the code for the functions below. # The starter code for each function includes a 'return' # which is just a placeholder for your code. Make sure to add what is going to be returned. (Python) # Part A. count_char # Define a function count_char(s, char) that takes a string and a character # and returns the number of times the given character appears in the string def count_char(s, char): # YOUR CODE HERE return # Part B. is_power_of # Define a function is_power_of(i,j) that takes 2 ints i and j # and checks if i is a power of j or not # the function should return True indicating that i is a power of j # otherwise return False def is_power_of(i,j): # YOUR CODE HERE return # Part C. longest_word # Define a function longest_word(s) that takes a string s # where s is a sentence made up of words separated by a single space " " # and returns the longest word in this sentence # if 2 or more words are tied as longest then return the one that occurs LAST in the sentence # if s is an empty string return an empty string def longest_word(s): # YOUR CODE HERE return
