Elements in the Range
You are given three numbers. Check if any of the numbers exist in the range from 10 to 20 (including 10 and 20).
Input
The first, second, and third lines of input are integers.
Output
The output should be either
True or False.Explanation
Given
a = 2, b = 4, c = 16, 16 is in the range between 10 and 20.So the output should be
True
Sample input:
2
6

Write a program that reads a single line of input and prints the first and last characters of the given input and prints the asterisk character (*) in place of the remaining characters.Input
pairs = [ (x,y) for x in range(5,1,-1) for y in range(4,1,-1) if (x+y)%3 == 0 ]
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.
