Write program to calculate the sum of the following series where in is input by user. (1/1 + 1/2 + 1/3 +..... 1/n)
Lorico [155]

Answer:

#here is code in Python.

#read the value n from user

n=int(input("enter the value of n:"))

#variable to store the total sum

sum_n=0

for i in range(1,n+1):

# find the sum of series

   sum_n=sum_n+1/i

#print the sum

print("sum of the series is: ",sum_n)

Explanation:

Read the value of n from user. Create and initialize a variable sum_n with 0. Run a for loop to calculate sum.Initially sum_n is 0, then for value of i=1  1/i will be added to the sum_n.Then in next iteration for i=1, 1/2 added to sum_n. Similarly loop will run util i equals to n.Then sum_n will store the sum of the

series.

Output:

enter the value of n:5

sum of the series is:  2.283333333333333
