Write a function named "changeCase" that takes an array of characters terminating by NULL character (C-string) and a boolean flag of toUpper. If the toUpper flag is true, it will go through the array and convert all lowercase characters to uppercase. Otherwise, it will convert all uppercase to lowercase. For example, if the array is {'H', 'e', 'l', 'l', 'o', '\0'} and the flag is true, then the array will become {'H', 'E', 'L', 'L', 'O', '\0'}. And if the flag is false, the array will become {'h', 'e', 'l', 'l', 'o', '\0'}

Scrabble Scrabble is a game where players get points by spelling words. Words are scored by adding together the point values of each individual letter. Define a function scrabble_score (word:str) -> int that takes a string word as input and returns the equivalent scrabble score for that word. score = {"a": 1, "c": 3, "f": 4, "i": 1, "1": 1, "o": 1, "r": 1, "u": 1, "t": 1, "x": 8, "z": 10} For example, "b": 3, "h": 4, "n": 1, Your Answer: == 20 assert scrabble_score("quick") assert scrabble_score("code") == 7 1 # Put your answer here 2 Submit "e": 1, "d": 2, "g": 2, "k": 5, "j": 8, "m": 3, "q": 10, "p": 3, "s": 1, "w": 4, "v": 4, "y": 4,

1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 1.

Prompt: In Python language, write a function that applies the logistic sigmoid function to all elements of a NumPy array. Code:   import numpy as np import math import matplotlib.pyplot as plt import pandas as pd   def sigmoid(inputArray):               modifiedArray = np.zeros(len(inputArray))               #YOUR CODE HERE:               return(modifiedArray) def test(): inputs = np.arange(-100, 100, 0.5) outputs = sigmoid(inputs) plt.figure(1) plt.plot(inputs) plt.title('Input') plt.xlabel('Index') plt.ylabel('Value') plt.show() plt.figure(2) plt.plot(outputs,'Black') plt.title('Output') plt.xlabel('Index') plt.ylabel('Value') plt.show() test()

Write a function called remove_punct() that accepts an array of characters and the number of items in the array as parameters, removes the punctuation (',', '!', '.') characters from the array, and returns the number of punctuation characters removed. For example, if the array contains ['C', 'p', 't', 'S', ',', '1', '2', '1', '.', 'i', 's', 'f', 'u', 'n', '!'], then the function should remove the punctuation characters. The function must remove the characters by shifting all characters to the right of each punctuation character, left by one spot in the array. This will overwrite the punctuation characters, resulting in: ['C', 'p', 't', 'S', '1', '2', '1', 'i', 's', 'f', 'u', 'n']. In this case, the function returns 3. Note: if the array does not contain any punctuation characters, then the array is unchanged and the function returns 0.

In C++ language, write a program to print "Junior" if the given array element starts with 'J' and print "Senior" if the array element starts with 's'. Print the name of the player and the message Junior" or "Senior" accordingly. string names [5] = {"J-Liam", "S-Naoh", "S-Elijah", "J-James", "S-Henry"};

Imagine that you are a biomedical engineer analyzing DNA sequences. You have numerical measurements from two different measurement sources, m1 and m2, both of which are arrays. Write a function named dna that takes these two arrays as inputs. It should return a character array string of nucleotides (represented by the letters A, C, G and T). For a given index, i, the nucleotide in the string is: - ‘A’ if m1(i) >= 0 and m2(i) >= 0 - ‘C’ if m1(i) < 0 and m2(i) >= 0 - ‘G’ if m1(i) >= 0 and m2(i) < 0 - ‘T’ if m1(i) < 0 and m2(i) < 0    code to call the function  m1 = [-2 -3 2.5 0.3]; m2 = [1.1 2.1 -0.8 0.1]; sequecne = dna(m1,m2);  function dna    Please use MATLAB

In C++  please ! Write a Program that: Initializes an interger array size of 10 with random intergers in range [10,30]. Use a function named 'initialized_array' to acheive that. Determine if all array elements are distinct from each other or not.Use boolean function  named 'distinct_elements' to achieve that function 'distinct elements,  if the elements in the array are duplicate print out, elements are duplicate if not print out array

Create a program in C Language that calculates a student's overall grade based on their assignments, quizzes, and exams. Create three separate arrays of `double` which will store 5 assignments, 3 quizzes, and 2 exams, respectively. The program should prompt the user to enter the grades for each group on one line (see example). The program should then compute the average of each individual group and then weight that group based on the value given for the corresponding weight. In the example run below, the average assignment score is first calculated and then multiplied by the given assignment weight. The final grade is calculated as the sum of all weighted groups and should be printed to 2 decimal places. Submit your code as grades.c Other Requirements Do not hard code any values. Use preprocessor directives or `const` globals for array sizes. Your code must use consistent formatting and spacing. Points will be taken off for inconsistent or sloppy code. Example Run Enter 5 assignment…
