How do I replace break and continue but have the function do the same thing
PLEASE READ THE QUESTION! answer as soon as possible, thanks in advance no need to explain very clearly, just need the answer (and maybe a little explanation, but not as important since i know how to do it, i just need to check my work against the right answer)
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…
write a recursive version. The function takes two string parameters, s1 and s2 and returns the starting index of s2 inside the first string s1, or -1 if s2 is not found in s1. You must not use any loops; you also cannot use the string member functions find or rfind. You may use the member functions size, at and substr. Your function must be recursive. CANNOT MODIFY GRAY AREA
Complete the following function using pass-by-reference: void findMax(int &max, int a) which assigns value ‘a’ to ‘max’ if a > max. Write a pseudo-code then implement a program in C language to find the maximum in a sequence of numbers using this function.
please do in Haskal programing and explain how it is done ?
Write a function which takes two integer parameters for values to be added together and returns the result by value. The function may not print anything or read anything directly from the user (i.e. no cin/cout in the function). Assume that the values passed to the function will not be negative, but could be 0 or positive, and will both be integers. The function must implement addition recursively, and cannot use the standalone + operator (only ++) or call any other functions.

text = "ALICE was beginning to get very tired ofsitting by her sister on the bank, and of havingnothing to do: once or twice she had peeped intothe book her sister was reading, but it had nopictures or conversations in it, " Using R This is a bi-gram write a function that predicts a set of possible nextwords in a given partial sentence.The function will take three inputs:(1) sentence: the starting of a sentence as a character string, ex. “Hello, how are” and(2) n: the number of words to return that might come next in the sentence. The firstreturned word should have the highest probability of coming next, the second wordshould have the second highest probability, and so on.(3) trans_mat: a transition matrix from a previously fitted markov model.The function should base its predictions on the last bigram of the partial sentence.Note: if there are less than n words that can be generated based on the text, then have yourfunction only return these.
uestion 42: Return whether a string consists of a single letter In the function below, return True if the input string parameter consists of a single uppercase letter; otherwise, return False. Most solutions would do this in two logical steps: first testing if the string consists of a single character and, second, testing whether that character is one of the uppercase letters (which can be done by seeing if it is alphabetically between A and Z, inclusive).

What does this function do? def f2(s): i=len(s)-1 while(i>=0): print(s[i),end=") i=i-1 A) It prints the reverse of its parameters B) It counts the number of 'a' characters in its parameter s It counts the number of 's' characters in its parameter s It prints its parameter s Question 6 What's wrong with this code? i=10 while(i>100): print('Ali') i=i+1 It produces nothing
