Modular exponentiation is a very important building block of modern cryptography, which is the way our messages and traffic are encrypted and kept secure and private as they are transported across the internet. Recall: The modulus operation is Read More

For this week's code challenge, we'll be taking a simple look at a common problem in Computer Science. For this problem, you're going to read in an array that has an unknown number of cycles in it. In this case, each element in the array points Read More

For this week's coding challenge, we're taking a look at the problem of finding minimum distances in sets of points. Data for the problems below as well as some helper code can be found here: Read More

For our inaugural weekly coding challenge, we're starting with a classic. A palindrome is a sequence of characters that is the same both forwards and backwards. Examples of this are the words 'racecar' and 'madam' or numbers like 101, 111, 2882, and Read More
