TīmeklisJust observe that whenever you sum digits, 9s and multiples are ignored 9+9+9 = 27 => 2+7 = 9 9/18/27/36/45/54/63/72/81/90 => they all lead to 9 Also any number added to it, say 4, will result in the same 9+4 = 13 => 4 therefore once you make the first big sum you will only care about the reminder. 1+2+3+4+5+6 = 21 => 2+1==3 OR 21%9==3 TīmeklisMy effort on making the recursive way: public int sumRecursive () { Node newNode = new Node (item,next); int sum = 0; int result; if (newNode == null) { result = 0; } …

Tīmeklis2024. gada 22. aug. · The idea of the recursive approach is to consider all subsets of items and find whether there exists a subset whose sum equals "sum". While considering an item, we have one of the following two choices: Choice 1: The item is included in the optimal subset—decrease the sum by the item value. Tīmeklisimport java.math.BigInteger; public class RecursiveDigitSum { // method 1 -> recursive solution static int digitSum (String n, int k) { long superDigit = getSuperDigit (n); long n1 = getSuperDigit (superDigit); long k1 = getSuperDigit (k); long result = n1 * k1; while (result / 10 != 0) { result = getSuperDigit (result); } return (int) result; } TīmeklisEn Java, le mécanisme d'appel de fonction prend en charge the possibility of having a method call itself. Cette fonctionnalité est connue sous le nom de recursion. Par exemple, supposons que nous voulions additionner les entiers de 0 à une valeur n: public int sum(int n) { if (n >= 1) { return sum (n - 1) + n; } return n; } dr david wright qub
