How to make object as callable video __call__
from collections import Counter
class MyCounter(Counter):
Add here required code so that we can give data to object like co1("intel")
co1 = MyCounter()
co1("intel")
from collections import Counter
class MyCounter(Counter):
Add here required code so that we can give data to object like co1("intel")
co1 = MyCounter()
co1("intel")
Python
For example, an array A = [10, 20, 30] and a value x = 25.
We have values 10, 20, 30 at indices 0,1,2 respectively.
- Here index 0 is invalid because
- 10 + 25 = 35 is less than 20 + 30 = 50
- Here index 1 is valid because
- 20 + 25 = 45 is greater than 10 + 30 = 40
- Here index 2 is valid because
- 30 + 25 = 55 is greater than 10 + 20 = 30
So there are 2 valid indices.

Python
A number N is given as input. Write a program to check if N is positive or negative.
N = -12.5. As the value of N is less than 0, the output should be Negative.
Python
Sum of the series
Write a program to find the sum
S of the series where S = x - x^3 + x^5 + ....... upto N terms.
Input
The first line of input is an integer
X. The second line of input is an integer N.
Explanation
If we take
X value as 2 in the series upto 5 terms.
Then the series is 2 - 23 + 25 - 27 + 29
So, the output should be
410.
