leetcode 1837. The sum of the digits in the K-base representation

Given an integer n (base 10) and a base k , please convert n from base 10 to base k, calculate and return the sum of the converted digits.

After conversion, the individual digits should be treated as decimal digits, and their sum should also be returned in decimal notation.

Example 1:
Input: n = 34, k = 6
Output: 9
Explanation: 34 (decimal) is represented as 54 in hexadecimal.5 + 4 = 9 .

Example 2:
Input: n = 10, k = 10
Output: 1
Explanation: n itself is base 10.1 + 0 = 1 .

Tip:

1 <= n <= 100
2 <= k <= 10

class Solution {public:int sumBase(int n, int k){int he=0;while(n){he+=(n%k);n/=k;}return he;}};
