Question

Python question:

Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is:

As long as x is greater than 0 Output x modulo 2 (remainder is either 0 or 1) Assign x with x divided by 2

Answer 1

#Reading a decimal number input from user
num = eval(input("Enter value: "))
#Result is used to store binary value
result = ""
#Repeat the loop till n becomes negative
while (num > 0):
    #Finding the reminder
    rem = num % 2
    #Appending reminder to the result
    result += str(rem)
    #Making num to its half
    num = num // 2
#Reverse the value of result
result = result[::-1]
#Printing final binary value to screen
print(result)
