Complete the check_strings_same_start(word1, word2) function which is passed two string parameters. The function returns True if the two parameter strings start with the same character and only one (not both) of the parameter strings has an even number of characters (including any space characters), otherwise the function returns False. For example: Test Result result = check_strings_same_start("blue", "bag") True print(result) print(check_strings_same_start("babyproofing", "baby")) False print(check_strings_same_start("check", "fact")) False
Let L = {dog, cat, fish), the correct statements are: The first 10 elements in L* in lexicographic order are cat, dog, fish, catcat, catdog, catfish, dogcat, dogdog, dogfish, fishcat. The first 10 elements in L* in lexicographic order are €, cat, dog, fish, catcat, catdog, catfish, dogcat, dogdog, dogfish. The first 10 elements in L* in lexicographic order are e, cat, dog, fish, catcat, catdog, catfish, dogcat, dogdog. dogfish.

Part (a) Write a python function that computes the binomial coefficient ("). The function should return the correct answer for any positive integer n and k where k=m pass Part (c) Suppose that the number of people in the trial is 100. Then: • Plot a curve that shows how the probability of type 1 error changes with the choice of m, for m = 1,...n assuming that the null hypothesis holds (in red), • On the same picture, plot the probability of type 2 error vs the value of m in the case in which the new drug is effective with proability 0.68 (in blue). You can plot the two curves using matplotlib.pyplot. You can select the color by passing color='r' or color='b' to the plt.plot() function. [4]: n - 100 # your code here def plot_curve (): pass [5]: plot_curve() Part (d) Based on the picture above, what value of m do you think would be suitable to keep both type 1 and type 2 error small at the same time? (You may assume that the company claims the new drug has 68% accuracy) [6]: # your…

] ] is_bipartite In the cell below, you are to write a function "is_bipartite (graph)" that takes in a graph as its input, and then determines whether or not the graph is bipartite. In other words, it returns True if it is, and False if it is not. After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs. print (is_bipartite({"A" : ["B", "C"], "B" : ["A"], "C" : ["A"]}), is_bipartite({"A" : ["B", "C"], "B" : ["A", "C"], "C" : ["A", "B"]})) This should return True False Python Python
Here is a function that is supposed to return True if word (any string) ends with "s" and False otherwise: def ends_with_s(word):if len(word) < 1:return False return word[-1] == "s" Here is the test function I am using to test ends_with_s: def test_ends_with_s(): assert(ends_with_s("cats")) # option 1 assert(ends_with_s("") is False) # option 2 assert(ends_with_s("apple") is False) # option 3 assert(ends_with_s("S")) # option 4 Rewrite ends_with_s so that the test passes
3. Experiment with the following code for different strings assigned to s: S = # yourstring goes here for c in s: if c.isupper () : print (c) 4. Write a function upper that behaves as follows, i.e. it returns the substring of capitalized letters.
Q8: use Python Write a function return_odd that will take a list as its input and return a list of all the odd values as its output. Note that this differs from what you did above in two ways: (1) it returns the values, not the index, and (2) it's looking for odd values, not even. For example: >>> return_odd([1, 2, 3]) [1, 3] >>> return_odd([2, 4, 6]) [] In [ ]:
5. use c code to Write a stringSearch function that gets two strings one called needle and the other called haystack. It then searches in the Haystack for the needle. If it finds it, it returns the index of where the needle starts in the haystack. If the needle cannot be found, it should return -1 Prototype: int stringSearch(char needle[], char haystack) Example1: Haystack: “This is just an example” Needle: “just” Result: 8 Example2: Haystack: “This is just an example” Needle: “This” Result: 0 Example3: Haystack: “This is just an example” Needle: “this” Result: -1 Hint: all the answer need to include an output and use c code to answer
2. For each of the following sets, determine whether each of these statements is true or false. Write T or F. _e. {x} C {x} f. {x} C {{x}} g. {x} € P({{x}}) _h. {x} C P({x}) La. 0 E Ø _b. {0} C Ø _c. Ø E {0} _d. {ø} C {Ø, {Ø}}
rin t] (Replace strings) Write the following function that replaces the occurrence of a substring old substring new_substring in the string s. The function returns true if string s is changed, and otherwise, it returns false. bool replace_strings(string& s, with new substring a const string& old_string, const string& new_string) Write a test program that prompts the user to enter three strings, i.e., s, old_string, and new_string, and display the replaced string.
4. Complete the function show_upper. This function takes one parameter - a string (s). It should return a string made up of all the upper-case characters in s. For example, if s is “aBdDEfgHijK” then show_upper should return “BDEHK”. It should return the upper-case string - not print it. Do not change anything outside show_upper.
