    1837 - Sum of Digits in Base K.

    Easy

    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
