Explanation:

A number that is equal to the sum of the factorials of its digits is known as a Krishnamurthy Number, or Strong Number. As an illustration, 145 is a Krishnamurthy number since 1! + 4! + 5! = 145
1! + 4! + 5! = 145.

Steps:

  1. The factorial function computes the factorial of a given digit.
  2. The number is converted to a string to allow iteration over each digit.
  3. For each digit, its factorial is calculated and added to a running total.
  4. Finally, the total sum of the factorials is compared to the original number. If they match, the number is a Krishnamurthy Number.
