SPECIAL FACTORS

Ram loves playing with integers. He has a positive integer N. He wants to find special factors of the number. A factor is a number which exactly divides the given number. A factor is special if it is a prime number. Help ram by identifying all the special factors of the number.

INPUT : The input is a single line containing a positive integer N.

OUTPUT : The output should be a single line containing the space-separated prime factors in ascending order

EXPLANATION : In the example, the given number is 20.

the factors of 20 are 2, 4, 5, 10 Whereas the prime factors are 2, 5.

So, the output should be 2 5

sample input1 : 20

sample output1 : 2 5

sample input 2 : 45

sample output2 : 3 5

Identify and execute the respective operations in the following expression using regular expression and functions:

(5+3)*(8+4) 

This means you have to first execute the addition operation by implementing the addition function first then execute the multiplication operation

Input: (5+3)*(8+4)

implement the following operations using python: addition, subtraction, multiplication, and division  

segregate the patterns begins and ends with parenthesis together with the operations between them: (5+3), *,(8+4)

identify the operations inside each parenthesis and extract the operands: 5,3,+and 8,4,+

call the appropriate function along with the respective arguments: add(5,3), add(8,4) and then call multiplication(8,12)

Calculate the gradient decent formula for logistic regression

Maria has 4 bags while going to the airport she has been told that she take an average 50kg . Tell her to input the weight of each bag and calculate the mean weight

SPECIAL NUMBERS

you only like numbers that start with an odd digit. anil gives you space-separated integers as input . your task is left-rotate every number in the list (if required) so that can be liked by you.

NOTE:

1. if there is no odd digit in the number , do not rotate it.
2. if a number starts with an odd digit , do not rotate it

INPUT :

The first line of the input contains space-separated integers

OUTPUT:

The out should be a single line containing space separated integers with odd digit as first digit for each number.

EXPLANATION:

in the example, input is 21, 503, 256, 550, 86, 979, 281

Rotate all the words to the left so that each number starts with an odd digit .

Input1: 21 503 256 550 86 979 281

Output 1: 12 503 562 550 86 979 128

Input 2: 2001 463 6219 669 473 1006 77734 110 20511

Output 2: 1200 346 1962 966 734 1006 77734 110 511120

Distinct Characters

Andy has the word W and he wants to print the unique characters in the word in the order of their occurrence.

write a program to help Andy print the unique characters as described above.

NOTE : consider lower and upper case letters as different

INPUT:

The input is a single line containing the word W

OUTPUT:

the output should be a single line containing space separated characters

EXPLANATION:

in the example, the word is MATHEMATICS

The unique characters in the given word are M, A, T, H, E, I, C, S, in the order of occurrence

so the output should be M A T H E I C S

sample input1 : MATHEMATICS

sample output1 : M A T H E I C S

sample input2 : banana

sample output 2 : b a n

Given a string write a program to print the mirror of string in Alphabetical order to create a secret message

Note Mirror means a with z , b with y and so on

I have a problem of solving to get the average of 1st quarter, 2nd quarter, 3rd quarter and 4th quarter of list and this is the code.

    self.studName = []

    self.gender = []

    self.stQ = []

    self.ndQ = []

    self.rdQ = []

    self.thQ = []

  def newStudent(self,newStud,studGender):

    self.studName.append(newStud)

    self.gender.append(studGender)

  def studGrades(self,first,second,third,fourth):

    self.stQ.append(first)

    self.ndQ.append(second)

    self.rdQ.append(third)

    self.thQ.append(fourth)

    print("Student Grade 1st Quarter: ", first)

    print("Student Grade 2nd Quarter: ", second)

    print("Student Grade 3rd Quarter: ", third)

    print("Student Grade 4th Quarter: ", fourth)

  #average

  def Average(self):

    for i in self.stQ,self.ndQ,self.rdQ,self.thQ:

      sums = self.stQ[i] + self.ndQ[i] + self.rdQ[i] + self.thQ[i]

      avg = sums / 4

      print(avg)
