What is a palindrome, armstrong, mersenne numbers?

A numeric palindrome is a number that remains the same when its digits are reversed.

An Armstrong number of three digits is an integer such that the sum of the cubes of its digits is equal to the number itself.

A Mersenne prime is a prime number that is one less than a power of two.

Step-by-step explanation:

An example of a palindromic number is 16461.

371 is an Armstrong number since 3^3 + 7^3 + 1^3 = 371.

A Mersenne is a prime number of the form Mₙ = 2ⁿ − 1 for some integer n.
