def fquartic(x): return (x**4-1) Find the roots There are two real roots of this function. Even though you may immediately see what those roots are, use scipy.optimize.root_scalar to find those roots one by one: Use the default method (i.e. don't specify a specific method for root finding) Specify appropriate x0 and x1 values for each one of the roots (don't pick them right on top of the roots, but pick them close) Make sure that the converged attribute of your solutions are both True.

def fun_a(cards): """ cards is a list of int numbers ranging between 0 to 12 inclusive. We use the number to represent the card's rank in a deck of card. 0 is '2', 1 is '3', ...,9 is 'J', 10 is 'Q', 11 is 'K' and 12 is 'A' This function is to check if there is four of a kind in the cards (4 cards of the same rank) and a fifth card as a kicker to form a four of a kind hands with 5 cards total. The 5 cards look like this: x x x x y (x might be the same as y). If there is more than one way to form such a hand with given cards, choose x that has the highest ranking (that has 4 cards of rank x), and choose y that has the highest ranking in the remaining cards after removing 4 x's. return (x, y) if such a hand exists. otherwise return None.

Add a loop over to this function that tracks how many times the sum functions is called. Also explain how the loop is working. int64_t sum(int64_t N, uint64_t A[]){ int64_t sum = 0; uint64_t indx = A[0]; for (int64_t i = 0; i < N; i++){ sum += A[indx]; indx = A[indx]; } return sum;}
Python please: Complete the calc_factorial() function that accepts an integer parameter n and returns the sum of all integers from 1 to n. For example, if n = 5 then the sum of all integers from 1 to 5 is 1 + 2 + 3 + 4 + 5 = 15 Example: If the input list is 5 then the returned sum factorial will be 15 For simplicity, assume the input n > 0.
Given string stringVal on one line, integer idxStart on a second line, and integer choiceLen on a third line, replace choiceLen characters with "1234", starting at index idxStart. Ex: If the input is: Fuzzy bear 3 4 then the output is: Fuz1234ear Note: Using a pre-defined string function, the solution can be just one line of code. #include <iostream>#include <string>using namespace std; int main() { string stringVal; int idxStart; int choiceLen; getline(cin, stringVal); cin >> idxStart; cin >> choiceLen; /* Your code goes here */ cout << stringVal << endl; return 0;}

• get_tokens_from_equation(line): Takes one string as input that contains any combination of digits from 0-9 and the following mathematical symbols: + - x / = ^ (O The string does not have to correspond to a valid mathematical equation. For example, '4-3=0' and '4xx5=(8' could be valid inputs to this function. The function will translate the string into a list of tokens. A token is a single non-negative number (of any length) or a single mathematical symbol. Numbers should be added to the list as integers, and symbols as strings. The tokens in the list should be in the same order as the numbers/symbols appear in the string. For example, given the string '52-2=50', the function should return the list [52, '-', 50]. >>> get_tokens_from_equation('4=3') [4, '=', 3] >>> get_tokens_from_equation('6-5=15^4/2') [6, '-', 5, '=', 15, '^', 4, '/', 2] >>> get_tokens_from_equation('288/24x6=18x13x8') [288, '/', 24, 'x', 6, '=', 18, 'x', 13, 'x', 8]
Programming in C language. RandomNumbers Declare an integer array locally with the size of 200. Create a program that asks the user how many numbers the have. Use your getChoicel) function from before. Make sure it does not exceed 200 as the locally declared array has the size of 200. Use a loop to assign random numbers from 1 to 10000 to the array elements. (Remember to use srand() to seed the random number generator). Use a second loop to display each number, and also determine the average of all values in the array. You must also find the largest and the smallest numbers. After the for loop, display the average of all numbers. This program will let you enter a list of numbers into an array. It will then display all of the numbers, and finally display the average of all numbers. How many numbers would you like to enter?10 Number 1 is 42 Number 2 is 8468 Number 3 is 6335 Number 4 is 6501 umber 5 is 9170 Number 6 is 5725 Number 7 is 1479 Number 8 is 9359 Number 9 is 6963 Number 10 is…
