Answer:
see description
Explanation:
clicking in new script, we type the following:
%inputs and variables
N = input('Enter N : ');
values = input('Enter values : ');
positive=0;
negatives=0;
zero=0;
%for loop
for c = 1:N
if values(c) > 0
positive = positive + 1;
elseif values(c) < 0
negatives = negatives + 1;
else
zero = zero + 1;
end
end
positive
negatives
zero
so we basically loop the array and add one to counters each time we read an element from the input, for example if we enter:
Example input
Enter N : 5
Enter values : [1,-1,0,2,352]
positive = 3
negatives = 1
zero = 1
You use conditional formatting on a cell if the numbers are less then zero.
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
