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.
Three Divisors - LeetCode
WebExamples. In 22 ÷ 2 = 11, 22 is the dividend, 2 is the divisor and 11 is the quotient. If, 45/5 = 9, then 5 is the divisor of 45, which divides number 45 into 9 equal parts. 1 ÷ 2 = 0.5, the divisor 2 divides the number 1 into fraction. In the below-given example, 5 is the divisor, 52 is the dividend, 10 is the quotient and 2 is the remainder. WebSep 19, 2024 · Mixed up 15^k with 15k.
