Can you solve this real interview question? Sum of Digits in Base K - Given an integer n (in base 10) and a base k, return the sum of the digits of n after converting n from base 10 to base k. After converting, each digit should be interpreted as a base
Instructions In this kata, you must create a digital root function. A digital root is the recursive sum of all the digits in a number. Given n, take t

We’re looking for the sum of digits. When we get past nine, the sum of digits for ‘10’ is just ‘1’. The answer for N=12 should be 51, not 78.(For the record, when I’m performing a coding interview, my goal is to find out if you can code, not if you are good at ...
sum of digits G URAL 1658 题意:构造一个数x,使得这个数的数位之和等于n,每个数位的平方和等于m,求最小的 x 。 题解:设dp[i][j] 代表构造的数的数位之和为n,数位的平方和为j的最短长度。同时用pre[i][j]记录构造的数的首位。 cf - E题 题意:自己去看。 题解:借鉴网上一个大佬的思想。
洛谷CF1409D Decrease the Sum of Digits 洛谷 题号CF1409D Decrease the Sum of Digits 思路:数码的含义是各位之和(如213,2+1+3=6)。首先判断数码是否<=s,满足则直接输出0,否则因为如果不进位,那么数码肯定会越加越大,所以我们从右往左扫描这个数字(因为低位的位权小,进位代价低),然后把该位置为0(也...

解释:操作如下: - 转化:"leetcode" ➝ "(12)(5)(5)(20)(3)(15)(4)(5)" ➝ "12552031545" ➝ 12552031545 - 转换 #1:12552031545 ➝ 1 + 2 + 5 + 5 + 2 + 0 + 3 + 1 + 5 + 4 + 5 ➝ 33 - 转换 #2:33 ➝ 3 + 3 ➝ 6 因此,结果整数为 6 。 提示: 1 <= s...
Given an integer number n, return the difference between the product of its digits and the sum of its digits. Example 1: Input: n = 234 Output: 15 Explanation: Product of digits = 2 * 3 * 4 = 24 Sum of digits = 2 + 3 + 4 = 9 Result = 24 - 9 = 15 ...
Write a Python program to calculate sum of digits of a number. Pictorial Presentation: Sample Solution: Python Code: # Prompt the user to input a four-digit number and convert it to an integer.num=int(input("Input a four-digit number: "))# Extract the thousands digit (x).x=num//1000...
