Python
Perfect Squares in a Range
You are given two given numbers,
A and B where 1 <= A <= B, Write a program to find the number of perfect squares in the range A to B (including A and B).
Input
The first line of input is an integer
A. The second line of input is an integer B.
Explanation
In the given example,
A = 9 and B = 100. The perfect squares in the range A to B are
3 * 3 = 9
4 * 4 = 16
5 * 5 = 25
6 * 6 = 36
7 * 7 = 49
8 * 8 = 64
9 * 9 = 81
10 * 10 = 100
So, the output should be
8.

Sum of 1 series
Given integer
N as input. Write a program to print the sum of series 1 + 11 + 111 + .... N terms.
Input
The first line of input is an integer N.
Output
The output should be an integer representing the sum of series.
Explanation
Given
N = 4
The sum for first
4 terms is 1 + 11 + 111 + 1111
So the output should be
1234.

Number of digits until N
Given an integer
N, write a program that prints the count of the total number of digits between 1 and N.
Input
The input is a positive integer.
Output
The output should be a single line containing the count of the digits up to the given number.
Explanation
Given
N = 10
From 1 to 9, each number contains a single digit. From 10 onwards, the numbers contain two digits.
So the output should be 9 + 2 =
11.

D as input, write a program to display the day name.
(1 - Monday, 2 - Tuesday, 3 - Wednesday, 4 - Thursday, 5 - Friday, 6 - Saturday, 7 - Sunday)
Input
The first line of input is an integer
D.
Output
The output should be a string representing the day name.
Explanation
For example, if
D = 3 then, according to the day number, the day should be Wednesday.

Python
Compute Hypotenuse
Write a program to find the hypotenuse
H of a right-angled triangle of sides A and B.
Note: Pythagoras theorem states that, for a right-angled triangle. Hypotenuse2 = A2 + B2
Input
The first line is an integer,
A. The second line is an integer, B.
Output
The output should be an integer.
Explanation
In the given example, the first side
A = 3, and the second side B = 4. To calculate the hypotenuse we use Pythagoras theorem.
According to Pythagoras theorem, hypotenuse2 = 32 + 42
Therefore, the hypotenuse value is
5. So, the output should be 5.
