The average or arithmetic mean of a collection of numbers is calculated by adding the numbers and then dividing it with the number of numbers in the collection. The arithmetic mean is used in almost all scientific disciplines for analysis. Consider the collection of numbers – 5,7,8,12. The arithmetic mean is (5+7+8+12)/4 = 8. There […]

The factorial of a number n is defined as the product of all integers from 1 to the number n. For example, the factorial of number 5 is 1*2*3*4*5 = 120. Factorial of number n is represented as n!. For larger values of n, the factorial value is very high. The factorial of zero by […]

The following python program demonstrates how to perform AES 256 encryption and decryption using the pycrypto library. Please note that this example is written in Python 3. First ensure that pycrypto library is installed on your system by running the following command, pip3 install pycrypto In the following python 3 program, we use pycrypto classes […]

MD5 is a message digest algorithm used to create a unique fixed size value from variable input data. MD5 is commonly used to check whether a file is corrupted during transfer or not (in this case the hash value is known as checksum). Any change in the file will lead to a different MD5 hash […]

The following python program uses the bubble algorithm to sort a list of numbers. The program allows the user to input the list of numbers from the console. Please note that bubble sort is a very inefficient algorithm and hence is not recommended in production code with large data. # Bubble sort in python # […]
