WebFeb 20, 2024 · The idea is simple, we find all divisors of a number one by one. For every divisor, we compute sum of digits. Finally, we return the largest sum of digits. An efficient approach will be to find the divisors in O (sqrt n). We follow the same steps as above, just iterate till sqrt (n) and get i and n/i as their divisors whenever n%i==0. WebJan 25, 2015 · This may give you more of the theory or logic that you want behind this (I give an explanation of your example specifically at the end), although Marco does provide a nice, intuitive combinatorial analysis.
