Write a function that will accept a list of numbers and an integer (n). The function should return a list containing every nth item from the input list, always starting with the first item in the list. The original list should not be modified.

For example, if the function is passed the list

[8, 3, 19, 26, 32, 12, 3, 7, 21, 16]

and the integer 3, it will return the list

[8, 26, 3, 16]

If the function is passed the list

[8, 3, 19, 26, 32, 12, 3, 7, 21, 16]

and the integer 4, it will return the list

[8, 32, 21]

The function should be general, and work for any list and any value of n.

The code in python is given below.

def nthElement(oldList,n):
    newList=[]
    newList.append(oldList[0])
    i=n
    while(i < len(oldList)):
        newList.append((oldList[i]))
        i+=n
    return newList

n1=int(input("Enter number of elements in the list: "))
inputList = list(map(int,input("\nEnter the numbers : ").strip().split()))[:n1]
n=int(input("Enter the value of integer: "))
newList=nthElement(inputList,n)
print(newList)

Write a function that will accept one integer matrix E and one column vector F by reference parameters, and one integer I as a value parameter. The function will return an integer v, which is the i-th coefficient of row vector denoted by E*F (multiplication of E and F).

Write a function decimalToBinary(n) that converts a positive decimal integer n to a string representing the corresponding binary number. Do the conversion by repeatedly dividing the number n by 2 using integer division, keepting track of the remainders, until the number is reduced to 0. The remainders written in reverse order form the binary number string. Do integer division of 5 by 2, so that N//2 is 2 with remainder 1. Now divide 2 by 2 to get 1 with...
