Answer 1

# Python3 program for the above approach
 
# Function to find the sum of series

def printSeriesSum(N) :


     

    sum = 0;

 

    for i in range(1, N + 1) :

 

        # Generate the ith term and


        # add it to the sum if i is


        # even and subtract if i is


        # odd


        if (i & 1) :


            sum += i / (i + 1);


      

        else :


            sum -= i / (i + 1);


     
 

    # Print the sum


    print(sum);

 
# Driver Code

if __name__ == "__main__" :

 

    N = 10;

 

    printSeriesSum(N);
