The Joy of Computing using Python

Week 4: Programming Assignment 1 - Factorial

Due on 2021-09-02, 23:59 IST

Write a program that takes a number as input and prints its factorial as output.

Input Format:

Single line of input contains a number

Output Format:

Display the value of the factorial corresponding to the input

Example:

Input:

3

Output:

6

--Solution-- 

  import math a=int(input()) print(math.factorial(a),end="")

Week 4: Programming Assignment 2 - Multiples

Due on 2021-09-02, 23:59 IST

Given a list of n integers, count the number of integers in the list that are either a multiple of 3 or a multiple of 5. (All the numbers are guaranteed to be distinct).

Input Format:

Single line of input contains a list of space separated integers 

Output Format:

Print the count of numbers that are divisible either by 3 or 5

Example:

Input:

1 3 5 6 7 9 11 13 15 18 20 21

Output:

8

--Solution-- 

a=input().split() count=0 for i in a: if int(i)%3==0 or int(i)%5==0: count+=1 print(count,end="")

Week 4: Programming Assignment 3 - Arrangements

Due on 2021-09-02, 23:59 IST

Given a list of binary numbers (0s and 1s), determine the number of possible arrangements of distinct binary sequences using given 0s and 1s.

Input Format:

Single line of input containing 0s and 1s

Output Format:

Print an integer value indicating the number of possible arrangements using given 0s and 1s

Example:

Input:

0 1 0 1

Output:

6

Explanation:

For the given input, the possible distinct binary sequences that can be formed are : 0011, 0101, 0110, 1001, 1010, 1100.

Hence the output is 6.

--Solution-- 

import math a=input().split() c=a.count('1') b=a.count('0') ans=int(math.factorial(len(a))//(math.factorial(b)*math.factorial(c))) print(ans,end="")
