1837. Sum of Digits in Base K

https://leetcode.com/problems/sum-of-digits-in-base-k

Description

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 10 number, and the sum should be returned in base 10.

Example 1:

**Input:** n = 34, k = 6
**Output:** 9
**Explanation:** 34 (base 10) expressed in base 6 is 54. 5 + 4 = 9.

Example 2:

**Input:** n = 10, k = 10
**Output:** 1
**Explanation:** n is already in base 10. 1 + 0 = 1.

Constraints:

• 1 <= n <= 100

• 2 <= k <= 10
