A worm as a multicell organism, but a virus is a single cell.
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
<h2>
APPEND ONLY</h2>
Unlike traditional databases, blockchain is designed to be an "append-only" data structure. That means you can only append new data in the form of additional blocks, which will then be chained together with previous blocks of data. All data is permanently stored across more nodes and cannot be altered.
No it is not. it's quite simple when you get the hang of it
