HackerRank Recursive Digit Sum problem solution

WebAug 25, 2024 · As discussed in this post, recursive sum of digits is 9 if number is multiple of 9, else n % 9. Since divisibility and modular arithmetic are compatible with multiplication, we simply find result for single occurrence, multiply result with x and again find the result. How does this work? Lets N = 24 and X = 3. So, sumUntilSingle (N) = 2 + 4 = 6.
