Python 6. Sum of Numbers Design a function that accepts an integer argument and returns the sum of all the integers from 1 up to the number passed as an argument. For example, if 50 is passed as an argument, the function will return the sum of 1, 2, 3, 4, ...50. Use recursion to calculate • the sum.

Write a RECURSIVE function, without using any loops, that prints the contents of a matrix with 3 columns.  The function should take the matrix and the number of rows as arguments. void print_matrix(int arr[][3], int num_rows);

Implement the following function: Code should be written in python.

. Explain through an example and with tables how the k-means clustering algorithm would cluster a dataset containing 4 objects, each with three coordinates c. Explain using an example how StandardScaler can support clustering.

Q5/ write a program to compute the value of R from X,Y and Z values which are X=[0,1,2......9], Y= [2,4,6,.,20], and Z=(1,3,5,...,19]. Print the values of X,Y,Z, and R as adjacent columns. R = √A²+B²+C² X √x² + y² +2² A = . B=√36X* +9Y²+252² T C = √9+sin³Y+Z MATLAB

9. Write function getMoveRow to do the following a. Return type integer b. Parameter list i. 1-d character array (i.e. move), size 3 c. Convert the row portion of the player’s move to the associated integer index for the board array d. Example: i. move = ‘b2’ ii. 2 is the row iii. 2 is index 1 in the board array e. Return the row array index that corresponds to the player’s move f. Return a -1 if the row is not valid (i.e. INVALID) 10. Write function getMoveCol to do the following a. Return type integer b. Parameter list i. 1-d character array (i.e. move), size 3 c. Convert the column portion of the player’s move to the associated integer index for the board array d. Example: i. move = ‘b2’ ii. b is the column iii. b is index 1 in the board array e. Return the column array index that corresponds to the player’s move f. Return a -1 if the column is not valid (i.e. INVALID)      I am getting an error when entering the code at the very end. please fix it.  This is the code in C     int…

# dates and times with lubridateinstall.packages("nycflights13") library(tidyverse)library(lubridate)library(nycflights13) Qustion: Create a function called date_quarter that accepts any vector of dates as its input and then returns the corresponding quarter for each date Examples: “2019-01-01” should return “Q1” “2011-05-23” should return “Q2” “1978-09-30” should return “Q3” Etc. Use the flight's data set from the nycflights13 package to test your function by creating a new column called quarter using mutate()

Q#8, Recursive letter: Given the following recursive function: 1 def love_letter(n):2 ifn<1:3 print('I Love CS5001 - Yes I do!!!') 4 else: 5       print('Roses are Red, Violets are Blue') 6          love_letter(n - 1)   Identify the code lines that contain the base case and describe its purpose How would you modify this code to produce infinite recursion? Write a version of this code that will run forever and/or generate a RecursionError while still printing each message from line 3 and 5 at least once.
