Question

mick and rose Students do not like programming and they do not have a subject so they decide to play a simple game, where rose hands a group of negative and positive numbers, so rose converts negative numbers to zeros and positive to ones Then the result is converted to a decimal number, for example 5 8-9 0 -5 7 10101, and then we convert the result 10101 = 21 and the output is decimal using python or c++ write program like this sample input and output

Sample Input 0 :

5

12 34 -3 4 -3

Sample Output :

26

Answer 1

I used a predefined function to convert the binary number to the integer.

please drop a comment if there's a problem

#-----------------------SAMPLE RUN--------------------------------

5

2 34 -3 4 -4

-OUTPUT-

26

#-----------------------------------------------------------

#reads the first number

len=input()

#reads the the list of number and converts to a list

nums = input().split()

binary = ""

#iterates over the nums list

for i in nums:

    #checks if the current number is greater than equal to0

    if int(i) >= 0:

        #inserts a 1 at the end of the binary

        binary = binary + "1"

    else:

        #inserts a 0 to the binary

        binary = binary + "0"

#converts the binary into an integer and prints the number

print(int(binary, 2))
